摘　　要：从夫琅和费衍射积分公式出发，论述了不同遮拦比的双反射光学系统的I。（环）／I。（孔）的测量原理和测试方法，并通过计算和测试取得了一系列有实用价值的数据。从而，为某些红外光学系统设计时合理地选取遮拦比提供了依据。In this paper, it is upon the integral formula of Fraunhofer diffraction that the data of I.(annulation)/ I.(aperture) are studied theoretically and experimentally while the obscuration of a double reflection optical system is varied. Some valuabledata are abtained and may be of use for supporting practical infrared optical system design.
