摘要：
A rotation-invariant photorefractive correlator is reported in this paper. Matched filters synthesized with reference patterns at different rotational angles are stored in the photorefractive medium via angular and peristrophic multiplexing. During the recognition process, the input image is compared with all the reference patterns in parallel. The feasibility of the proposed correlator is demonstrated by experimental results.
