knife-edge testing

基本解释

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果相比較，騐証了數字刀口檢測方法的可行性，爲鏡麪誤差的加工脩正提供了依據。
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，完成了實騐裝置設計，建立了數字刀口檢測的實騐裝置。
