ABSTRACT:
Method and apparatus for determining a backscatter radiation component of a ring laser. Electro-optic apparatus provides to a ring laser resonant cavity, during a first interval of time, a clockwise propagating radiation beam and also provides, during a second interval of time, a counter-clockwise propagating radiation beam. Other electro-optic apparatus measures, during the first interval of time, a magnitude of a backscatter radiation component resulting from the clockwise propagating radiation beam and also measures, during the second interval of time, a magnitude of a backscatter radiation component resulting from the counter-clockwise propagating radiation beam. The measured backscatter magnitudes are input to a processor for calculating a lock-in characteristic of the ring laser. The measured backscatter magnitudes are also optionally input to a display device for displaying, in conjunction with signals expressive of the clockwise and counter-clockwise propagating beams, a relationship between a beam and its resulting backscatter component.
