Measurement system for diffuse reflectivity based on LabVIEW

Laser diffuse reflectivity is an important parameter of target's optical properties, it usually can be measured by absolute measurement method and relative measurement method. Based on the principle of laser diffuse reflectivity, a test flap was built up by measuring the energy of the reflected laser and the incident laser based on LabVIEW. This software can accomplish real-time data acquisition, data processing, storage, query and other functions. The system can not only measure the reflecting features of out-field target using absolute measurement, but also improve the accuracy of diffuse reflectivity using relative measurement. Experimental results prove that this system has high measurement accuracy and control precision, good stability and reliability, high automation level, convenient operation, it has very high practical value to measure reflecting features.
