九、光学传递函数的测量由第三节的讨论,我们已经知道光学传递函数是根据成象的频波过滤理论导出的,它首先应用于光学系统的象质评价,在实验评价方面就是光学传递函数的测量。在前面已曾导出或直接写出了关于传递函数H(f)的表示式(15)、(16)和(33),这几个式子在含义上尽管有些不同,但描述的都是同样的物理量,(16)式更是(15)式中把物分布取
Measurement of Optical Transfer Function As discussed in the third section, we know that the optical transfer function is derived from the imaging frequency-wave filtering theory. It is first applied to the evaluation of the image quality of an optical system, and in the experimental evaluation it is the optical transfer Measurement of function. The expressions (15), (16) and (33) for the transfer function H (f) have been derived or written directly from the previous, which, although somewhat different in meaning, describe the same Of the physical quantity, (16) type is (15) where the distribution of things to take
