为了解决菲涅尔光学助降系统的检测问题，提出了一种基于成像式照度探测法的菲涅尔灯发光强度测量方案，并研制了成像式照度探测装置。试验结果表明该装置可远距离对大口径、大发光角度的菲涅尔灯进行发光强度的探测，满足菲涅尔光学助降系统检测装置测量的要求。

In order to address the problem of measuring the Fresnel Lens optical landing system,a measurement method which based on imaging illumination detection should meet the technical index is proposed. According to the analysis of the measurement’s requirement,a imaging illumination detector is designed. Experiment results show that such detector,has high measuring speed and eliminate background light interference characteristics,can measure the luminous intensity of fresnel lens optical system which has long-distance and large divergence angle and match the measurement’s requirement.
