High-precision acoustooptical receiver (frequency meter of the combined type)

An algorithm is suggested and experimentally checked for information reading about the energetic center coordinates of a diffracted light spot. The algorithm is applied to acoustooptical microwave receivers (frequency meters) with allowance for the technical and constructive features of the modern element base, in particular multielement photoreceiving devices. The algorithm provides the possibility of measurement accuracy increase of the radio signal carrier frequency 10 times.
