Abstract

The optical heterodyne correlator (OHC), in which the functions of overlapping and fast scanning by reference image relatively signal image and light frequency shift between them are realized with the hologram lens scanner (HLS) in JFT plane is described. The important advantage of this scheme is that any phase distortions of amplitude spatial filters (ASF) inserted in the imaged JFT plane do not affect output response. That provides high instrumental accuracy of OHC and wide possibilities for adaptive processing with using controllable ASF and matrix photodetectors. Presented results of experiments demonstrate high performance of this scheme. Multichannel fiber optical communication between the imaged JFT plane of OHC scheme and elements of radio antenna array permits fast and soft beam forming and scanning by computer controlled optical transparencies and HLS.
