Title: Fibre-optic gyroscope
Inventor: VARNHAM MALCOLM P
IPC: G01C19/72
Filed: 1989-03-09
Abstract: In a fibre optic gyroscope, the sensitivity of the gyroscope to offsets introduced by the demodulator 17 is reduced by means of an optical phase modulator 8 to which first and second modulation signals are applied, and by a second demodulator 19. A generator 11 produces a waveform 12 of frequency 2/T where T is the transit time of light through the coil 2, and a chopper 14 operating at a lower frequency periodically inverts the waveform 12 to produce the phase modulation signal 15. Demodulator 17 operates at the generator frequency 2/T, and the second demodulator 19 operates at the chopper frequency and minimizes any offset from the first demodulator. A voltage controlled oscillator 31 generates a sawtooth signal 29 which is applied to phase modulator 9 to null the phase imbalance and determine the incremental angle or rate values. <IMAGE>
