MICRORESONATOR FIBER-OPTICAL CONVERTER OF PHYSICAL QUANTITIES Russian patent published in 1999 - IPC

Abstract RU 2135957 C1

FIELD: temperature, pressure and acceleration measurements. SUBSTANCE: proposed converter of physical quantities has fiber-optical laser, one butt of light guide of which being mated to collimator to form parallel beam of light on to reflecting surface of microresonator. Second butt of light guide is output one and is connected to spectrum analyzer via photodetector. Reflecting surface of microresonator is positioned at some specified angle with respect to axis of collimated beam of light. Free-running operation in system "fiber-optical laser-microresonator" is conducted thanks to modulation of amplitude of reflection factor of optical resonator of fiber-optical laser or to modulation of Q-factor of two-mirror optical resonator due to photoinduced angular deviations of one of mirrors in which capacity reflecting surface of microresonator is used. EFFECT: improved stability of measurement results. 2 cl, 4 dwg
