Fiber Optic Gyroscope For Continuous Measurement Of Low And High Rates Of Rotation

View page
US Patent:
7072043, Jul 4, 2006
Filed:
Oct 15, 2003
Appl. No.:
10/686215
Inventors:
Donald I. Shernoff - White Plains NY, US
International Classification:
G01C 19/72
US Classification:
356460
Abstract:
A fiber optic gyroscope includes a light source and a phase modulator coupled to an optical fiber coil. Light from the source is divided into a pair of first light signals that are directed into opposite ends of the coil to counter propagate through the coil and produce corresponding second light signals the relative phases of which are shifted by the modulator. In one embodiment, a waveform generator defines a modulation waveform so that a determined sequence of five or more phase shifts are set between the second light signals, including shifts of zero degrees, +90 degrees, −90 degrees, +180 degrees and −180 degrees. The second light signals interfere with one another to define a recombined light signal, and measurement signals corresponding to the intensity of the recombined light signal are obtained for each phase shift in the sequence. A rate of rotation of the coil is determined continuously in accordance with the measurement signals and a given interference function.

Controlled Light Source

US Patent:
44319479, Feb 14, 1984
Filed:
Jun 4, 1982
Appl. No.:
6/384853
Inventors:
Lincoln Ferriss - Lincoln Park NJ
Donald Shernoff - White Plains NY
Assignee:
The Singer Company - Little Falls NJ
International Classification:
H05B 4136
US Classification:
315151
Abstract:
A feedback control system for maintaining the intensity and spectral distribution of light at a predetermined level at a wavelength characteristic of the excited source. Control of that intensity, which exhibits a systematic but not necessarily a monotonic relation with excitation, is achieved by measuring and controlling the intensity of flux at another characteristic wavelength which is both systematic and monotonic.

Laser Power Monitoring Optics For A Ring Laser Gyroscope

View page
US Patent:
48773115, Oct 31, 1989
Filed:
Jan 19, 1988
Appl. No.:
7/145021
Inventors:
Donald I. Shernoff - White Plains NY
Assignee:
Kearfott Guidance & Navigation Corporation - Wayne NJ
International Classification:
G01C 1964
US Classification:
356350
Abstract:
Instead of using two power monitoring photodiodes and associated summing circuitries for adding the power of the laser beams circulating in the cavity of a ring laser gyro, the present invention eliminates one of the photodiodes and uses, in its stead, reflective means for directing both of the laser beams onto the remaining power monitoring photodiode, which automatically measures and sums the light intensities or power from the laser beams and provides as an output the thus added power directly to the necessary electronic circuitry to maintain constant the pathlength of the cavity.

Dither Compensator For Ring Laser Gyroscope

View page
US Patent:
45360871, Aug 20, 1985
Filed:
Jun 8, 1983
Appl. No.:
6/502370
Inventors:
Donald Shernoff - White Plains NY
Assignee:
The Singer Company - Little Falls NJ
International Classification:
G01C 1964
US Classification:
356350
Abstract:
Dither compensation in a ring laser gyroscope is effectuated by one or more retroreflective prisms or by one or more pairs of cofunctioning transparent wedges mounted to the gyroscope casing in a dither compensation plane parallel to the plane of the laser light path in the gyroscope cavity. Prisms or beam splitters reflect at least one of two counter-rotating laser beams to the dither compensation plane from the plane of the cavity. An optical sensor comprising a photodiode for detecting and analyzing the interfering laser beams can be placed in the dither compensation plane or in the plane of the gyroscope cavity.
