中文摘要：
龙虾眼光学聚焦系统是一种模仿龙虾视觉的光学系统,适用于卫星平台上的软X射线成像探测.根据掠入射原理,分析和计算了Angel型龙虾眼光学系统采用不同金属镀膜时光子能量和全反射临界角、反射率的定量关系;提出一种计算龙虾眼光学系统有效探测面积的方法,推导了相关的理论计算公式并进行了蒙特卡罗仿真试验,理论计算值与蒙特卡罗仿真结果吻合很好,龙虾眼X射线光学系统在110keV能段的有效面积与光子能量近似呈负指数关系,具体的参量与镀膜的粗糙度有关.
英文摘要：
Lobster-eye is an optical focusing system that simulates the lobster vision,and is very suitable for appling in the X-ray pulsar imaging detection on the satellite platforms.Based on the principle of grazing incidence,theoretically quantitive relationship between photon energy and full reflection critical angle and reflectivity for different metallic film are studied.A method for calculating the effective detection area of the Angel lobster-eye optical system is proposed,and formulas are duduced.MontelCarlo experiment results is agree with the theoretical figure.In the range of 110 keV,the effective detection area of the lobster-eye optical system is approximately negative exponential function of photon energy,specific parameters depending on film roughness.
