Abstract : The patent describes a receiver for an optical radar using a two-dimensional array of microlens image dissectors which completely fills an area of an image plane. Each microlens is directly coupled to a mixer-detector element. The array is adapted to be illuminated with returned focus radiation from a remote reflecting target and with a planar wave of optical energy from a local oscillator. The output signals of the mixer-detectors are analyzed and used to orientate the array such that the maximum amplitude output signal corresponds to the central microlens of the array.
