绝大多数情况下,一个光学系统的像质应该用一种以上的质量标准来描述。作为两种彼此独立的质量描述的可能性,是在林福特(Linfoot)标准基础上,用海特尔(Hertel)的“清晰度”(Schroffheit)和“真实性”(Treue)概念来描述的。本文提出了一种新方法,即海纳赫数(He-ynacher-Zahl)”和“极限分辨率”像质描述法。对几个小画面物镜的测量表明,这两种描述方法有类似性。 In most cases, the quality of an optical system should be described by more than one quality standard. The possibility of being two independent quality descriptors is based on the Linfoot criteria, described by Hertel’s concept of “clarity” (Schueoffheit) and “truth” (Treue) . In this paper, we propose a new method, the He-ynacher-Zahl and the limit-resolution image quality description.The measurement of several small-screen objectives shows that the two methods have similarities .
