METHOD OF ELECTRIC SIGNALS AMPLIFICATION Russian patent published in 2010 - IPC H03F17/00 G02B26/08 G02F1/39 H04B10/00 

FIELD: electricity.

SUBSTANCE: method for amplification of electric signals consists in their conversion into spatial oscillations of optical beam, amplification of these oscillations by amplitude and conversion into electric signal. Conversion of electric signals into spatial oscillations of optical beam is carried out with the help of piezoelectric plate with mirror reflecting surface. In order to amplify spatial oscillations of optical beam by amplitude, plates may be used with mirror reflecting surfaces facing each other. Such amplifier does not contain active and passive radio elements, therefore its pass band is practically unlimited, and in case of high accuracy of mirror surfaces, its non-linear distortions are insignificant. Besides it does not have stability limit and may provide for high amplification ratio, without change to self-excitation mode. Conversion of spatial oscillations of optical beam into electric signal is carried out by means of correlation treatment of optical radiation at entrance pupil of photodetector.

EFFECT: increased sensitivity, noise immunity, electromagnetic compatibility and security of equipment functioning, reception and processing of electric signals.
