本文提出了一种新的双折射共光路干涉法,并结合自动数据处理系统,用于测量大凸球面。该干涉仪可以消除系统误差,获得准确的测量结果。精度约为(lambda)/50,准确度约为(lambda)/10。
We have developed a new birefringent common-path interferometric method incorporating an automatic data processing system for testing large convex spherical surfaces. This interferometer can eliminate system errors and achieve accurate results of measurement. Precision is about (lambda) /50 and accuracy is about (lambda) /10.
