This paper is to introduce both a construction method for a Cylindrical Hologram and a work world of Ray’s Cylindrical Hologram through research about coexistence of between visible world and invisible world, since the first work, in 2007. ‘Green Apple’ of the Cylindrical Hologram, was issued, then a broad range of Cylindrical Hologram works have been completed following an improvement of a weak point that it is impossible to observe a portion of shadow occurred by a illumination in the construction of the previous Cylindrical Hologram. The Hologram works based on theme “coexistence of visible world and invisible world” has been exhibited four time in Korea between year 2011-2012. In addition, during the exhibition, works done by KETI using Holographic printer will be introduced as well. “I do hologram works. I work over and over for making false images through holograms with familiar, everyday, and current objects and photographs. It is the work process of a hologram that reappearances things and grants them permanence in terms of sustaining them. The world of wave is part of the world of invisible. It is not visible of sound wave, brain wave, and wavelength. Therefore it is clear that we live in coexistence of visible as well as invisible world. From the Theory of relativity by Einstein, it could be acknowledged that the visible is relative to the invisible. Through the quantum theory, exemplified by the story of Schrödinger’s cat, it could be resulted according to imagination or observation before watching outcomes from experiments. What we can interpret through this story is that things can be taken off as we imagine and the false image of hologram coexists in the visible “life”.
