摘要
在相机研制中,杂光系数是评价杂散光的主要指标.为了快速、便捷、准确地计算杂光系数,本文通过分析透射式光学系统的杂散光路,根据能量传输原理,推导了无中心遮拦无渐晕的透射式光学系统的杂光系数的理论计算方法,并编制了相关的程序.仿真结果表明:该方法简单易行,能够快速给出杂光系数的初步评价,将杂散光抑制设计及分析提前,为后续设计提供参考.
In the camera design,veiling glare index is a main criterion to evaluate the stay light.In order to quickly,easily and accurately calculate the veiling glare index,the stray light paths were detailed analyzed.The formula of fast-calculating the veiling glare index was deduced and programmed.It was indicated that the proposed method is an easy way to estimate the veiling glare index and it will betterment the following design.
