Study on Dynamic Measurement Method of Visible and Near Infrared Light Radiation during P^rotechnical Combustion

摘要

In this paper, it introduces the dynamic measurement method of visible light and near infrared light radiation during pyrotechnic combustion, measurement system design method and the program design of data sampling and processing based on Labwindows/CVI. In order to adapt field operation, the data acquisition card with USB interface and notebook PC are used in this system. Furthermore, this measurement system is so portable by using the powerful software function of Labwindows/CVI. Multiplex signal sampling and real-time data processing can be realized in this measurement system and all functions have been tested in actual experiment. The main characters of this measurement are well function expansibility and simple operation.
