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 hologram lens scanner (HLS) in JFT plane is describe.d The important feature of the collinear heterodyning is non-sensitivity of its output response to any phase distortions of an amplitude spatial filters (ASF). That provides high instrumental accuracy of OHC and wide possibilities for adaptive processing with using controllable ASF and matrix photoreceiver with controllable sensitivity of each element. 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 or acoustic antenna array permits fast and soft beam forming and scanning by computer controlled optical transparencies and HLS.
