  • Patent number: 4563092
    Abstract: The invention relates to a laser rotation rate sensor wherein two light beams counterrotate in a polygon equipped with reflectors at its corners, a signal being derived from their frequency difference in dependence on the rate of rotation. The rotation rate sensor comprises a reflector designed and operated as a magneto-optic element for the suppression of lock-in and including a prism whose base boundary face is disposed adjacent a layer of a gyrotropic material, the reflector being designed in such a manner that total reflection occurs. In the laser rotation rate sensor, the index of refraction of the gyrotropic material is approximately equal to or greater than that of the prism; a further layer of a dielectric material is disposed adjacent the gyrotropic layer, which further layer has a smaller index of refraction than the prism material and the material of the gyrotropic layer, in such a manner that total reflection occurs at the interface between the layer of gyrotropic material and the further layer.

  • Patent number: 4556320
    Abstract: The invention relates to a laser rotation rate sensor wherein two light beams counterrotate in a polygon equipped with reflectors at its corners, a signal depending on the rate of rotation being derived from the frequency difference. One of the reflectors employed is designed as a magneto-optic element so as to suppress lock-in. This reflector includes a prism whose base boundary face is provided with a layer of a material having a lower index of refraction than the prism material. At least one of these materials is a gyrotropic material. Almost no reflection occurs when light enters the prism at the two lateral faces due to adherence to the Brewster condition. Further, the angle of incidence of the beams on the interface with the layer having a lower index of refraction than the prism material is so large that total reflection occurs.
