Paper Abstract

A method for the recording of a rainbow hologram with multiple objects at different depths in a single exposition is presented. The created hologram can be observed under white incoherent light and shows three letters R, O, and X where the R is closest to the observer at surface level and the other two letters are placed at 2mm increments into the hologram. A spatial light modulator containing the information of a binary computer-generated hologram (CGH) of the three letters is illuminated with a 632.8nm HeNe laser. The reconstructed hologram is projected on a photosensitive film and interfered with a plane wave acting as a reference beam for 90s and then developed.
