AI Technical Summary
Existing technologies require disassembling the product for measurement during the fault location process of the forward channel of a fiber optic gyroscope, which poses a risk of damage and is highly complex, affecting the normal detection accuracy of the fiber optic gyroscope.
An automatic test system for the forward channel gain of a fiber optic gyroscope was designed. The system generates closed-loop control signals and gain test drive signals through an FPGA processor, and calculates the forward channel gain using the voltage difference output by a photodetector, thus avoiding interference with normal closed-loop detection.
It achieves non-destructive, fast, and accurate forward channel gain measurement, avoids affecting the normal detection of fiber optic gyroscopes, and simplifies system complexity.
