摘　　要：提出了一种用于测试新型LED精密进近航道指示器(PAPI)的光强度方法。运用光电技术和计算机技术,准确地测出LED-PAPI的光强度,使得指示器能够达到相关国际标准的要求,提高指示器信号的准确性,并且增加飞机着陆的安全性。A new method to measure the light intensity of Precision Approach Path Indicator based on LED is presented. The light intensity can be measured accurately by optic-electronic and computer techniques, which can make the indicator meet the international standards and improve the accuracy of the signals produced by the indicator. Thus aircrafts will land more safely.
