光学传递函数的研究

Study on Optical Transfer Function

光学传递函数是作为评价成像质量好坏的一种重要方法。通过数值计算的方法,依据一个具体的透镜的光学传递函数,利用分离变量的方法,算出了像屏上所成的像。总结了求解该类问题的一般方法,并对该方法的优缺点进行了阐述。

Optical transfer function is a effective method to assess the quality of the image. Optical transfer function of a specific lens is determined,and a image of the lens is calculated in the screen with separate variable by computer calculation. A general solution to such problem is given, and finally the advantages and disadvantages of the methods are illuminated.
