Abstract

An optical rotation sensor includes a Fabry Perot laser having an active gain medium for generating first and second light beams, a closed optical path through which the first and second light beams counter-propagate and first and second mirrors coupled to respective ends of the closed optical path. The first minor is a ring mirror having a complex valued reflectivity that varies with a rotation rate of a frame within which the optical rotation sensor is placed. A detector is coupled to an output of the Fabry Perot laser to measure an output intensity thereof.

Dependent claims

An optical rotation sensor, comprising:

a Fabry Perot laser including:
an active gain medium for generating first and second light beams;
a closed optical path through which the first and second light beams counter-propagate, the active gain medium being within the closed optical path;
and
first and second mirrors coupled to respective ends of the closed optical path, the first minor being a ring mirror having a complex valued reflectivity that varies with a rotation rate of a frame within which the optical rotation sensor is placed;
and
a detector coupled to an output of the Fabry Perot laser to measure an output intensity thereof.
