thank you for it I like to describe some of the thoughts behind the course that Latimer and have been working on there will be offered this fall at valid colored those colors in Irvine Calif or a dog environments just go
00:22
over generally objective and some of the methods and don't spend and the course what I call the rest of the story of lot and the people of a lot of the science the art and and ultimately what I think of as art critique the objective of
00:38
the course is to to try to get people knowledge to give the student's knowledge to understand and appreciate and enjoy and critique holograms and holographic art we will feel successful if these people leave being participants in some way and lot even if it's just as as a better more sophisticated audience
01:06
I think that in holography which in this field we need 5 different kinds of people we need this the collectors in these years sophisticated audience is what I call the audience in general will cost many artists when scientists when the technicians when the critics that I think it's really difficult to be more than 1 of these kinds of persons at 1 time I can say this because I found myself sometimes trying to be all 5 of them and I have a hard time choosing which 1 1 of the objectives of our courses to prepare some edited due to choose which of these areas to be the
01:50
promises that way we set out of this course is that we think that a person can understand a lot from a nonscientific mathematical point of view would make him more likely to be interested and involved in an hour a lot of urine holography is is an artist and critic collector teacher on just a spectator so we think that we we can offer this service and on mathematical description and understanding of almost a complete understanding of that will allow us to appreciate and enjoy a lot of In addition to that as you from China Justin's discussions here and and other discussions there's another dimension to holography 1 of the very rich history that also has a lot to do this we think that sort of thing can be part of the and of course also so we're going next and that type of material In general can use
02:58
little or no mathematics we're going to use graphical explanations and I'll show some of these we have individual projects gallery visits that the channel like an art appreciation class accepted the article we do plan although I don't think it's necessary for people to make holograms to enjoy that we do plan to have students make holograms in the clusters we're
03:25
gonna be addressing some we can answer questions that that challenge us has addressed here to get people to understanding the ability even assets questions and to discuss such questions questions that we all struggle with some of the sample and the course of where the applications where the new applications with great potential what should I think about being involved in so we are going to see 3 D movies 3 D TV in 3 D telecoms that's another thing worth discussing will graphic art ever really become recognized like the other art forms the many of these kinds of questions that I I think that even with the group made to address why have so many things popped up analyze century got all excited and then this can done away what I
04:23
call the little Paul Harvey calls this the rest of the story of sort of adopted this and I think the history of lot he has these many different stories that I'll be addressing and I'm not going to take time here because John is already mentioned some
04:40
of those me those it writes out of these 2 great men that were run in year today and out of their students and their coworkers and people who met were influenced by these for
04:54
the size of a lot of Prof 1st started teaching holography in 1968 it was a graduate course at a time and it was too often electromagnet 9 magnetic theory and I have to admit that that time we understood the mathematics equations but when it comes to really understanding have a clear physical pictures would get and the 1st release this when we 1st started teaching short courses 2 people were not mathematically inclined not physics and plant we couldn't really explain coherence interference who could explain that to these people so we started then looking for simpler ways to looking for ways to do it now mathematically that anybody can understood and understand I went through a whole series of these things In the case of physics things like the whole diagrams of but yields a person what he calls a column by the Fourier optics diffraction miles water analysis ultimately we started using more analysis and found out that this is the sort of thing that gave a picture that people can understand so eventually graduated to or maybe 1 still simpler understanding of all these things using more analogies and over the years developed a
06:26
lot of those techniques so that that's going to form the basis of explanation of these and I'll show some examples the the understanding already got is completely different things that as far as I'm concerned that in holographic artifact holograms are easy to make is irrelevant the painting easy to make also real making a great artworks is not the same in making a great is not easy a good artists if he is also a good technicians To make a great art holograms and and so on or with the help of a technician to make good on our even the technicians could accidentally stumble onto a great art holograms I think ultimately the viewer doesn't really have to know how holography works to appreciate enjoy article but he doesn't need to know how to look at the whole this model
07:34
of the the unusual most part of the Fourier explanation of the library is 100 sex the relies on mostly in his book which is a very nice book nonmathematical so this is 1 of the 9 mathematical methods if you of if you take the gradient is assigned weight you that slide into it practice into 3 directions and if you increase the frequency the angle here increases there is a superposition and optics this as if you had
08:14
these things together then you can get a multiplicity of angles so you can build ultimately anyway from whatsoever by adding cytosolic ratings and then ultimately any image that you would like so this is the this is the basis of fourier transform theory so I easy to understand still really more mathematical than
08:35
we really would like here would like to some people don't even know what a cosine wave this and they don't have to this go to the bottom 1 notice the the more a model if you look at the grading like this the can represent either away from this traveling from left to right Oricon represent a hologram has been made by 2 parallel waves mixing together if you guys weights together like this then you can illustrate very easily and especially with computers and PowerPoint and nowadays that you can do some really neat things of this also can be done with over here it's very nicely so they show how waves interfere and cancel and in fact when you bring them on an angle like this yourself a set of ranges from or a friend is here that are just like that in French ranges that would form those strangest but the the angle about sector angle between the 2 so if you place a places found in this area here at the then you can very clearly imagine the layers of several laying down into the emulsion like this 3rd 1 here shows up to waves of different frequencies add together to form the frequencies in each of these cases you can imagine this also as being a hologram and if you put 1 hologram on top of the other you get interference and songs all graphic interferometry comes up quite naturally who just using the
10:22
simple models you can explain that in a princeton from coherence effects of motion vibrations all the different things that happen in color and they're really very graphical no mathematics whatsoever you can explain speckled multiple wavelength our recontouring all the Kansas things that you can do it a lot with the 2
10:49
gratings together if you move the now you can see how
10:54
to waves interfere at
11:00
an angle again you see these phrases that form again is sparse sectors of
11:05
the angle so now now if we
11:17
place the emulsion here and how that system of reduced instead the emotions think those layers of silver reflecting light then if
11:29
the final grammar with an object wave and reference where an object and then you really that all grammar with a reference way then
11:48
using the object will reconstructing all of this is taken the macroscopic world xylography and placing it into a the visible model uh
12:01
it's easy to show that to spherical waves interfere spherical
12:04
and plane waves here they
12:08
are interfering and you can see the ranges of forming you see that if you just
12:16
this example and then like over where our friend must projectors out to flat plate then you can create an inline hologram or what would be his own plate and and so on so there's and many of you I'm sure know about this this is not something that happens region within developing these kinds of analysis for almost as long as a lot of his bed around now preaching in
12:44
appreciating all exams and all graphic art are a different story of appreciating how large as an art some same tools same vocabulary landform color texture all those are in art appreciation there are some that are not common to the other art forms the biography does have like dynamics concealment these are things that 1 uses to understand what is happening in the piece of art so that the goddess has all these tools in fact the heart has more tools and you would have with other art forms so the viewer can seek out what the artist has done in with what skill
13:33
is done taking a step further and the critiquing hold 1 can the remaining to attack types of disciplines of a completely different training 1 is the esthetics In the course the others technical the technical part of of the usual things that could be created with look at the peace and ask what is the visual impact what is the message the subject to the usual things of skill and artist users to create balanced movement repetition rhythm contrast and so on and then a cost concealment and surprise those are the same qualities that you could critique and George graphic art with and in the course and technical things how well do is a hologram made necessary really the technology and also how well is it displayed because in designing this saying you need to not only design and how it's going to be created but has again be reconstructed looked there and then finally all of those tools that 1 has the powerful things of the artists would have how well use some of what had is how well the exploit this medium what did he data that you can do with another medium I
14:55
won't go into the details but in the paper of have picked an example this is a wonderful piece there a critique then critiqued and detail in terms of all those factors that I just described this happens to be a piece it was in an exhibit and our professor looked at it and he says this is a lot this is just a threedimensional image and this is an illustration of what happens when a person doesn't understand the holographic contributions and things this picture speaks worlds of things you can talk about a critique so people have to understand it had to be educated along those lines with that I would invite
15:42
any comments and suggestions for this course the course and contributions to how we can improve it like to acknowledge these 2 men in black are also acknowledges with me these 2 men not only made this paper and our careers possible but actually made it possible for us to be friends so that thank you thank you and you and me you you don't all the time all you have to this is what in thank you it's a larger scientific community of 1 that Shannon mentioned many of come from a different community of about 15 years ago the the the Knights of holography was founded section founded by the hands wrote and he'd chose a person the thoughts of the united the bought sword and he made a big deal out of the United that is not exactly as a joke but just as a beginning In that started something so every year now the previous nite chooses the next hole and he goes and buys a sword and a parchment written in his own country language and at some society meeting that it's kept a secret that until the nite of the they that's ceremony and use the gas taken totally by surprise when he becomes nite becomes for the males against knighted in takes the oath and the Continental

and that next services is going to happen in France that the spectral 0 6 million this year about and it was
