grating shearing interferometer

基本解释

This method is realized by using laser grating shearing interferometer and Talbot effect.
這種方法是利用激光光柵剪切乾涉儀和塔寶傚應實現的。
This interferometer used grating as its shearing part. It has characteristics of simple light route, compact structure, low shockproof.
該儀器利用光柵作爲錯位元件，具有光路簡單，結搆緊湊，波像差小，防震要求低等特點。
CCD is used in double-frequency grating shearing interferometer to measure the time and space coherence of light field quantitatively and spherical aberration of gradient-index rod lens.
利用雙頻光柵剪切乾涉法，CCD攝像機採集剪切乾涉條紋圖，用自行設計的軟件對圖像進行処理，可定量測量光場的時空相乾性以及梯度折射率透鏡的像。
