摘要
A Sagnac effect optical gyrometer comprising a probe consisting of a plane spiral-shaped optical loop (2) produced by means of optical circuits on a substrate, comprising light guides for the propagation of two light waves from a light source (20) through the spiral in opposite directions. Both ends (10, 12) of the spiral guides are connected to devices for delivering (14) the two light waves to the spiral and detecting (16, 18) each of them as they leave it (2). Connection of the ends (10, 12) of the light guides with the light source (20) and the detecting devices (16, 18) is provided by a tricoupler (8) having three parallel rectilinear guides and being built into the same substrate as the spiral.
