Abstract: The working principle of dynamic detection technology for the luminous intensity of airport aid lights was researched, and the character of distance measurement in the dynamic detection of luminous intensity was analyzed. Based on the principle of Doppler ranging radar, a non-touch real-time distance measurement system was built. Combining with hardware card, measurement software was designed by using object oriented method. According to the multithread technology, the distance measurement and the light illumination measurement were made in different threads. The whole process of dynamic measurement of luminous intensity was autocontrolled. Test result shows that the synchronization of distance measurement and light illumination measurement is realized by using the system, the error of distance measurement is 5 mm, the process of dynamic measurement of luminous intensity can be controlled by using the distance measurement precisely, and the control precision of distance between illumination measurement points is up to 0.000 5%. So the system has good real-time performance, high measurement precision, and satisfies the request of real-time precise distance measurement.
