Analysis and Test of Starting Characteristics of Light Source Module for Fiber Optic Gyroscope

Start-up time of light source control system (light source + control circuit) have an import influence over quick response performance of fiber optic gyroscope. The system start-up characteristics are related to driver circuit in addition to light source. The system response speed and its stability can be accurately grasped by testing start-up performance of SLD light source control circuit designed for fiber optic gyroscope and analyzing the test results. It can be known from the test results that it takes around 2s from power-on to preliminary stabilization of optical power output.
