HIGHLY STABLE ANGULAR-RATE SENSOR Russian patent published in 2006 - IPC G01P3/36 G01C19/64 G01C19/72 

FIELD: fiber optics, applicable in designing of fiber-optic gyroscopes and other fiber sensors of physical quantities on the basis of a ring fiber-optic interferometer.

SUBSTANCE: the sensor has a laser diode, the first and second beam splitters, the first and second loop light-guide elements, phase modulator, fiber circuit and a differential amplifier, temperature-sensitive element, microcontroller, function power-independent storage, central user's equipment and a low-noise amplifier. The output of the differential amplifier is connected to the first input of the low-noise amplifier. The output of the temperature-sensitive element is connected to the information input of the microcontroller by means of a serial code wire. The output parallel wires of the microcontroller are connected to the address inputs of the power-independent storage. The microcontroller is connected to the respective input of the function power-independent storage by the sense wire, and to the respective input of the central user's equipment - by the "Start" wire. The analog output of the CUE is connected to the second input of the low-noise amplifier. The output of the low-noise amplifier serves as the output of the angular-rate sensor.

EFFECT: provided correction of temperature influence on the stability of the output characteristic.
