ANALOG CIRCUIT TO REDUCE RELATIVE INTENSITY NOISE

Systems and methods for reducing relative intensity noise are provided. The system can include a photodetector configured to detect the relative intensity noise of a light source. The system can include a transimpedance amplifier configured to provide a feedback loop with the photodetector to generate a first signal based on the detected relative intensity noise. The system can include a controller configured to actuate the light source based on the first signal to reduce the relative intensity noise. In this manner, the system can reduce the relative intensity noise of a light source for various optical systems, including gyroscopic systems.
