摘　　要：为了解决菲涅尔光学助降系统(FLOLS)的检测问题,文中根据FLOLS检测应满足的技术指标,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,并根据分析设计研制了成像式照度探测装置。通过试验,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 （FLILS）,a measurement method which based on imaging illumination detection should meet the technical index is proposed.According to the analysis of the measurement requirement,an imaging illumination detector is designed.Experiment results show that the detector has high measuring speed and eliminate background light interference characteristics, can be used to measure the luminous intensity of fresnel lens optical system which has long-distance and large divergence angle and match the measurement requirement
