ABSTRACT:
A laser gyroscope is disclosed wherein a polarization dispersive structure, disposed in the path of the laser beam, includes an anisotropic crystal as a half-wave retarder. The crystallographic axes of such crystal are oriented with respect to the plane of the path to produce different delays to oppositely polarized waves passing through the crystal structure.
