Abstract
In this work we present a single exposure method for recording multiple holograms in reflection holography. In this novel method, the input pattern is a segmented image composed of alternating slices of several original images and modulated by a lenticular lens array sheet. A set of object beams can be produced simultaneously, which are angularly separated on the recording plane and overlap one reference beam at the same time. Therefore, only one exposure is needed for holographic recording multiple holograms. Experimental results show that a lenticular lens array sheet placed as a modulator in the path of the object beam provides a simple yet effective ingredient of creating multiple images for single-exposure holography. The proposed method is especially useful for one-step write/read multiple holograms and for stereoscopic display applications.
