在光学零件制造中,用刀口仪阴影法检验光学零件的加工表面,就象样板的作用一样。现在来谈谈阴影检验和它的应用。阴影检验出现在十九世纪中期,当时加工天文仪器的镜面困难很大,不但耗费巨大的劳动,而且要靠熟练的技术才能完成,刀口阴影法就是在这种情况下产生的。用阴影法控制镜面形状直观、简单、灵敏度高,大大缩短了镜面加工时间,解决了当时天文光学工艺上的困难,促进了以 In the manufacture of optical components, the processing of optical parts with the knife-edge shadow method, as the role of the template. Now to talk about the shadow test and its application. The shadow test, which took place in the mid-nineteenth century when it was difficult to process astronomical mirrors, was labor-intensive and proficient in the art of knife-edge shadowing. Shading method to control the mirror shape intuitive, simple, high sensitivity, greatly reducing the mirror processing time, to solve the technical difficulties of astronomical optics, and promote the
