Abstract
A power control system for a ring laser gyro including a beam intensity readout. A monitor is coupled to the beam intensity readout for generating an intensity signal indicative of the intensity of the beam at an intensity signal output. A signal averager is coupled to the intensity signal output, the signal averager providing an average intensity signal at an average intensity signal output. An analog-to-digital convertor is coupled to the average intensity signal output for converting the average intensity signal output to a digital signal on a digital signal output. A processor is coupled to the digital signal output and generates a power control signal on a power control line in response to and in proportion to the value of the digital signal. A power supply is coupled at a programmable input to the power control line where the power supply means outputs a voltage signal on a voltage supply line coupled to a ring laser gyro electrode, where the voltage signal is responsive to the power control signal and the processor and power supply operate together so as to control a voltage signal in response to variations in beam intensity.
