ACOUSTIC-OPTIC ARRANGEMENT FOR DETECTION OF BROADBAND PHASE-SHIFT KEYED SIGNALS AND DETERMINATION AND DEFINITION OF THE KIND OF THEIR PHASE MODULATION Russian patent published in 2006 - IPC G01R23/16 

FIELD: the invention refers to the field of optical processing and may be used for analysis of receiving signals in multichannel and single channel systems of radio communication.

SUBSTANCE: the arrangement has a laser, a condenser, a collimator, an ultrasonic light modulator, an integrating lens and a matrix of n photoreceivers. Additionally there are two half-transmitting mirrors, a reflection mirror, two ultrasonic light modulators, two integrating lenses, two matrixes of n photoreceivers, a logical block, three groups of n stripe-filters, two groups of n amplifiers with quadratic characteristics, two groups of n mixtures and a generator of fundamental frequencies.

EFFECT: possibility of simultaneous detection of sinusoidal signals and phase-shift keyed broadband signals, determination of their carrier frequencies and the kind of their phase modulation signals.
