摘要
The Skip-Flat test and Ritchey-Common test are the well-known methods for large flat mirrors measurement. This paper describes the theories of two methods. The combination of the Skip-Flat test with Ritchey-Common test is proposed. Simulations and experiments of the combination method for testing the large rectangular flat of high aspect ratio are shown. The results of the combination test and direct measurement are presented. In comparison of the methods, the combination test is in good agreement with the direct measurement.
