Abstract: The airfield lighting system provides safety for the take-off/landing safe of aircraft at night or in low visibility environments. It is an important task to measure and judge quickly and accurately whether the light intensity level, light illumination angle, etc. meet the standards of the International Civil Aviation Organization (ICAO) to ensure the safe operation of the airport. In this paper, the illuminance detector based on the silicon photocell is designed. The visibility curve V(λ) is completed by the combination of cosine corrector and different filters, realizing the high-speed dynamic detection technology accurately. The linear calibration and dynamic accuracy measurement of the illuminance detection is completed by experiments. The illuminance measurement error rate and the dynamic measurement error meet the requirements of ICAO regulations. The high-speed dynamic detection of light intensity in parallel sections of navigation aids is realized.

Key words: illuminance detection, accuracy calibration, dynamic detection
