Dyachok Ya.I., Onufriev A.V., Yakubovskij M.I. «Acoustooptical analyzer of radiosignal spectra» Приборы и техника эксперимента, 34, № 5, с. 202-203 (1991)

An analyzer is designed for analyzing both continuous and impulse signals in a wide frequency range. The analyzer fields of application are: development of wide-band spectra analyzers to study on different physical processes, radioastronomy investigations, development of panning radioreceivers operating in real time scale. The analyzer is connected in the spatial integrating circuit and comprises optical radiation source, prismatic optical beam shaper, acoustooptical modulator, Fourier long-focal length lens, photoreceiver, read-out and signal processing circuit.
