本文以用红外视象管观察不可见影象为基础,叙述一种红外光谱区内使用的装校方法,并以检查胶合时道威棱镜组的相互位置为例研究了这个方法。此法也可用于装校其他光学组件和部件。被检验部件由四个道威棱镜(用硅做的)组成。众所周知,当光学系统的通光孔径 In this paper, based on the observation of invisible image by infrared image tube, a method of assembling the instrument used in the infrared spectrum is described. The method is studied by examining the mutual position of the Dove group during gluing. This method can also be used to mount other optical components and components. The components tested consisted of four Dove prisms (made of silicon). It is well-known that when the optical system has a clear aperture
