In order to realize the accurate measurement of the laser fuze optical power and the sensitivity, the fiber coupling technique was applied to laser fuze test equipment. After the analysis of the principle of laser fuze and laser coupling optical fiber characteristic, a design scheme of based on the optical fiber coupling wan was presented. A fiber coupled laser device with adjusting mechanism was designed to improve the fiber coupling efficiency. The attenuation device based on attenuation sheet combination and the optical system based on beam splitting prism were designed, the real-time adjustment and accurate measurement of the laser fuze echo were realized. By using real time control system based on the CAN bus and LabVIEW software modularization design, a good human-computer interaction interface was achieved. By using the measurement system analysis method, the measuring equipment accuracy, reproducibility and consistency were analyzed. The results indicate that the system can accurately measure the laser fuze optical power, and sensitivity, measurement accuracy can meet the requirements.
