with gleeful yielded win joined also for our inspection work because the idea is that when you want to make solar cells plastics you needed to 1st inspects and assured that everything is clean and free of contamination so what we're doing here is that we go beyond that Canada's will which Eastern cameras which can detect up to 5 500 none the particles and there's a lot of applications In nondestructive techniques for inspection of surfaces with applied this technique for optical inspection and dogged the local processing of plastic sheets for lodging solar cells think about them of article in the news 493 Waveland is very hard to detect so we have to find out ways to detect with very high signal-to-noise ratio and also should be nondestructive so nothing should fetch mission we should follow as a cheater and calls on their we should follow the signal in should follow whether the article comes fast and that sheets can hold any testimony presented his

about optical scan filming which is the technique used to be direct fire also wants to see the extent of smaller than 1 might think it is a very difficult problem unless something I like the fact American soldiers I'm
