摘要
从夫琅禾费积分公式出发 ,论述了双反射光学系统的I0环 I0孔 的测定原理和检测方法。并通过精确测试取得了一系列有实用价值的数据。
Starting with the integral formula of Fraunhofer diffraction, the paper describes the measuring principles and method of I_(0 annulation~/I_(0 aperture~ for different obstruction ratio of double reflection optical system. Valuable practical data are obtained by means of calculation and measurement.
