Abstract
A high resolution ring laser gyro readout is accomplished by attaching the readout detectors signals to appropriate circuitry that allows a digital signal processor to sample the signals coming out of the readout sensor. The digital signal processor can then provide sufficient processing to determine the phase and frequency characteristics of these output signals which are indicative of the rate of rotation and the direction of rotation of the laser block 10. By sampling at a rate that greatly exceeds the maximum anticipated readout frequency, the resolution of the present invention is greatly enhanced. Furthermore, the readout system of the present invention is capable of handling certain irregularities in the gyro's output.
