Published: March 2023
FIG. 7.19 (a) Vertical pendulum tilt sensor ( Dong et al., 2005 ) with three fiber Bragg gratings attached to three cantilevers. A tilt of the pendulum leads to bending of the cantilevers depending on the direction of the tilt. This leads the attached fiber Bragg grating to strain and change its reflection spectrum. (b) Schematic of a MEMS ring laser gyroscope with movable mirrors and lens. ( Hashimoto et al., 2009 ). (c) Schematic of a passive resonant optical gyroscope using a fiber ring. The phase modulators are driven by antiphase triangular waves to reduce parasitic effects and allow the readout of Sagnac phase shift as amplitude at photodetector ( Jin et al., 2007 ).

(a). Basic scheme of the ring interferometer. Light source S, beam splitter SP, mirrors M1, M2, M3, photographic plate or film P. The splitter divides the light and sends it both ways around the circuit, to reach the photographic plate, where the two components make an interference pattern. Sagnac mounted the entire apparatus on a turntable and rotated it at 120 rpm. (b). The modern version: laser light source L, beam splitter SP, many-turn optical fiber F, and electronic phase-difference detector E. Fig. 1. (a). Basic scheme of the ring interferometer.

...The interferometer described here was introduced by G. Sagnac in 1910. In its original layout it was a “rectangular” interferometer. It was used by Michelson and Gale in their determination of the effect of the earth’s rotation on the velocity of light. The “triangular” layout was used by Dowell...
