Abstract
A ring laser gyroscope system includes light intensity detecting devices for detecting intensity of laser beams in the gyroscope. A computer processes the output and calculates the amount of backscatter in each beam. The measurement of backscatter is used to calculate the amount of movement required of mirrors in the gyroscope to change the path length of the laser beams an amount sufficient to minimize the backscatter in each. By minimizing backscatter, random walk of the laser beam is reduced.
