Abstract

Angularly multiplexed transmission holograms were recorded at multiple spots on a photopolymer coated disk. By imaging in the `along track' direction and Fourier transforming in the radial direction when recording and presenting images, disk rotation can be used to generate the 2D correlation functions between stored templates and presented images. The correlation functions for holograms multiplexed at a given spot are generated line by line and detected in parallel. A theoretical model of operation was developed and experimentally verified.
