【摘要】 传递函数检测是CCD相机整机系统检测的一个重要技术参数。常规测试方法是条纹对比度法。研制一套主要用在实验室条件下的静态目标模拟装置,对CCD相机整机(光学系统、CCD器件、电子学系统等)的静态成像质量进行测试,并依据CCD相机各成像通道在Nyquist频率下的最高传递函数来确定CCD相机的焦面(无穷远景物像面)位置。考虑对比度法对像面照度的要求,系统中设计了克勒照明装置。经LightTools分析像面照度不均匀性小于±10%。更多还原

【Abstract】 Transfer function test of the CCD camera is important technical parameters.Conventional test method is fringe contrast method.Develop a set of static target simulation device,mainly used in laboratory conditions,the CCD camera machine(optical system,CCD devices,electronics systems,etc.)to test the static image quality,and based on each imaging channel of CCD cameras in the Nyquist frequency of the maximum transfer function to determine the CCD camera’s focal plane position(infinite vision of object-image plane).The contrast method to consider the requirements of the image plane luminance,System was designed lighting Kohler illumination.The analysis of image plane illumination non-uniformity by LightTools is less than ± 10%更多还原
