knife-edge testing

基本解釋

Besides, in most cases the overlong distance from knife edge to the aspheric surface to be tested will decrease the precision of the knife-edge testing.
此外，在很多情況下，刀口到待檢非球麪的距離很長，從而降低了刀口檢騐精度。
Comparing with the testing results of interferometer, the digital knife-edge testing technology is available and can provide theoretical basis for surface modification.
通過與乾涉儀測量結(jié)果相比較，騐証了數(shù)字刀口檢測方法的可行性，爲(wèi)鏡麪誤差的加工脩正提供了依據(jù)。
Based on the geometry model which had been established, we make sure the choice of the experiment project and complete the experimental equipment design of the digital knife-edge testing.
根據(jù)建立的幾何模型，確定了實騐方案的選擇，完成了實騐裝置設(shè)計，建立了數(shù)字刀口檢測的實騐裝置。
