针对大口径的凸非球面零件使用特殊材料 (如采用碳化硅 )时无法用传统的背部检验方法的难题 ,初步研究了计算全息法检测凸非球面的原理和方法。所研究的凸曲面为一扁球面 ,口径为 10 0mm ,通过设计得出了相应的结果 ,实现了新型光学元件———二元光学面在凸曲面检验中的应用 The principle and method of calculating the convex aspheric surface by using the holographic method are studied preliminarily for the problem that the traditional back testing method can not be used when the special material (such as silicon carbide) is used for large diameter convex aspherical parts. The convex surface studied is a flat spherical surface with a caliber of 100 mm. The corresponding results are obtained through the design and the application of the new optical element --- Binary Optics Surface in convex surface test
