ACOUSTO-OPTIC RECEIVER Russian patent published in 2017 - IPC H04B10/00 

FIELD: physics.

SUBSTANCE: acousto-optic receiver comprises a receiving antenna 1, a frequency converter 2, a mixer 3, a local oscillator 5, the first 6 and the second 12 multipliers, the first 7 and the second 13 narrow band filters, the first 8, the second 14, the third 15 and the fourth 16 amplitude detectors, the first 9, the second 17, the third 18 and the fourth 19 keys, an amplifier 10 of the first sum frequency, an amplifier 11of the second sum frequency, a laser 20, a collimator 21, the first 22, the second 23, the third 24 and the fourth 25 Bragg cells, the first 26, the second 27, the third 28 and the fourth lens 29, the first 30, the second 31, the third 32 and the fourth 33 matrix photodetectors.

EFFECT: expanding the operating frequency range of the acousto-optic receiver without expanding the frequency adjustment range of the local oscillator by using additional receiving channels.
