The New Real-time 3-D Imaging Technique by the Frequency Multiplexed PHB Hologram

Abstract

PHB (Persistent spectral Hole Burning) material is the frequency selective recording film, so that a large quantity of images can be recorded, i.e. theoretically 10^4 images at cryotemparature, by exposure of lights with slightly different frequencies. It does not need any aftertreatments such as development, fixing and others. These properties can be combined with holography leading to realtime 3-D imaging device. In this report, we show the demonstration of recording and regenerating tens of the frequency multiplexing holographic images in one film. We discuss the possibility of the new realtime 3-D device by PHB holography.
