ABSTRACT:
A ring laser gyroscope, which has a triangular quartz block with a triangular quartz tube assembly forming an outer cavity for one rotating beam and an inner cavity for an oppositely rotating beam, is provided. The problem of lock-in of the beams is avoided. A pair of anodes and cathode means are provided for energizing the beams. A mirror is mounted at each corner of the block for reflecting the beams with one mirror being a partly reflective mirror for passing through portions of the inner beam and the outer beam. Outside the partly reflective mirror are mounted a first mirror for reflecting the inner beam, a second mirror for reflecting the outer beam, and a beam combiner mirror for combining the beams. A frusto-conical mirror receives the combined beams and reduces the mean diameter of the outer beam. A fringe detector receives the inner beam and outer beam on an area or point on a face of the fringe detector, which provides a gyroscope output.
