ABSTRACT:
An alternative form of accelerometer is described herein in which an acceleration sensitive element (68, 69) is coupled to a deformable reflector (60) in a lasing cavity (58) to vary the radius of curvature of the reflector in response to experienced acceleration and hence to alter the beat frequency between two transverse lasing modes in the cavity to provide an output signal indicative of the acceleration.
