摘要： A laser digital path length control method and apparatus for precisely controlling a laser path length to obtain a laser mode and change a laser mode. The invention uses a microprocessor to control a path length control circuit that continuously adjusts the position of path length control mirrors. The mirrors may be positioned in response to the microprocessor to acquire a particular mode of the laser or change the mode of the laser. While the gyro mode is changed the microprocessor increases the gyro run current to prevent loss of gyro function returning the current to its normal value following the mode change. The microprocessor adjusts the position of the two path length control mirrors such that total path length follows a predetermined or dynamic range. The invention allows the calculation of volts per mode of the laser by providing a means to monitor laser intensity as a function of voltage supplied to the laser path length controllers. The method and apparatus of the invention may be used in a laser gyro to improve system path length control and to help compensate for changes in system component parameters.

摘要： The invention provides a laser gyro with a single transformer power supply. The power supply receives a single 15 volt DC supply that is converted to a 320 volt DC supply, a 280 volt DC supply and a 500 volt DC supply. The invention implements a Royer Oscillator by providing a transformer with four windings each center-tapped. Two control transistors control the output of the transformer. The invention also provides a high speed output controlled start-up to prevent meta-stability in the Royer Oscillator.

摘要： A dither control system for a laser gyro having a dither motor for dithering the laser gyro through a desired angular displacement, known as the command angle, in response to a drive signal. In order to help avoid saturation of the laser gyro, the dither control system reduces the command angle by command angle reduction data when the average drive signal applied to the dither motor exceeds a maximum drive value until the command angle reduction data reaches zero. The command angle reduction value is calculated by integrating the difference between the average drive signal and the maximum drive value.
