Separate photodetectors and preamplifiers of prior art path controllers are replaced with an electronic circuit using the outputs of gyro fringe detectors. A ring laser gyro ordinarily includes fringe detectors for producing a data signal. Thus, the same detectors are used to serve two purposes. Pathlength controller simplification and cost reduction is thus realized since it is unnecessary to mount and align separate photodetectors to a gyro and to connect these photodetectors via flexible connections to a vibrating gyro.
