Abstract: 1,086,898. Lasers. SPERRY RAND CORPORATION. Dec. 1, 1964 [Dec. 5, 1963], No. 48719/64. Heading H1C. [Also in Division G2] In a ring laser rotation rate sensor in which two contrarotating beams are heterodyned to produce a difference frequency which indicates the magnitude of the rate of turn of the supporting platform, in order to indicate the sense of turn a delay is introduced into the optical path which is different for the two beams, so that a beat frequency is produced at zero rate of rotation. As shown, plane mirrors 13, 14, 15, and spherical mirror 16, define a closed optical path in which helium-neon lasers 1-3 are positioned, the Brewster angle windows thereof producing beams which are plane polarized at right-angles to the plane of incidence on each of the mirrors 13-16. The clockwise rotating beam represented by vector 29 after passing through a Faraday rotator 19 has its plane of polarization rotated 45 degrees to position 30, is then passed through a block 21 of birefringent material and is then returned by a Faraday rotator 20 to its original plane of polarization as represented at 34. Similarly the anticlockwise rotating beam has its plane of polarization so rotated that it is represented at 31 as it passes through block 21, which, having its principal axes aligned to the perpendicular planes of polarization of the counter-rotating beams, provides a different refractive index, and thus different path length, for the two beams. Mirror 15 is semi-reflecting so that a portion of each beam may be taken to photo-detector 26. In a modification the Faraday rotators 19, 20, are replaced by quarter-wave plates which convert the vertically polarized beams into a pair of oppositely sensed circularly polarized beams, the material 21 being birefringent to light of such type.
