Color holography in PhotonLab - May 2017

Patrick Schäffer is working on his W-Seminar-Arbeit on the subject of holography and did the practical part in our students’ lab PhotonLab. With a special holography kit made by Lithilo he produced a hologram of a Rubik’s Cube. The set consists of three lasers in red, green and blue, with which he can produce a color hologram of any given object on a special film. The mixing of the three colors is a bit tricky, as the image has to contain the correct balance of colors. In doing holography one of the biggest problems ist the exposure time, but the holography kit contains the perfect solution for that: the special film can’t be overexposed.
