光学传递函数的研究

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。

Study on Optical Transfer Function

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.
