In order to improve the safety of flight test and meet the testing needs, a non-contact displacement measurement system based on laser mouse sensor was designed. The overall design of the hardware and software of the measurement system is given. The system uses the ADNS-9800 laser mouse sensor as the core to measure the axial displacement of the damper in real time. The 8051 nuclear microprocessor STC15W1K16S is used as the control core to realize the measurement data transmission And laser mouse sensor power-on reset control. Experiments show that the measurement error of the system is less than 0.2%, which can meet the requirements of flight test.
