Publication number: 20110274133Abstract: Systems and methods for improved ring laser gyroscope devices through mix ratio optimization are provided. In one embodiment, a ring laser gyroscope device comprises: a laser block assembly having a cavity therein that defines a ring shaped laser beam path around the laser block assembly, the cavity containing a fill gas mixture comprising Helium and Neon, wherein the laser block assembly is characterized as having a Neon depletion life limiter; and a readout assembly optically coupled to the laser block assembly. The readout assembly outputs a laser intensity monitor (LIM) voltage that represents optical energy within the cavity. The fill gas mixture has a Helium to Neon ratio richer in Neon than a ratio that would produce a peak LIM voltage from the readout assembly.Type: ApplicationFiled: May 5, 2010Publication date: November 10, 2011Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Christina M.

Patent number: 7916302Abstract: A method for maintaining measurement accuracy of a ring laser gyroscope is disclosed. The method involves periodically measuring a path length control voltage in the ring laser gyroscope over a prescribed temperature range. When a first path length controlled by the path length control voltage deviates at least one wavelength from a nominal path length, the method detects the change in the path length as a mode shift. For each mode shift, the method applies a path length correction to maintain the first path length at a target path length over the prescribed temperature range. The method can apply a correction to a measurement signal output of the ring laser gyroscope by adjusting a calibrated scale factor depending on an actual integer number of wavelengths achieved during a mode shift.Type: GrantFiled: May 18, 2007Date of Patent: March 29, 2011Assignee: Honeywell International Inc.Inventors: David O. Fellows, Ying Tan, Timothy J. Callaghan, Christina M. Schober
