grating shearing interferometer

基本解釋

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干涉儀和塔寶效應(yīng)實(shí)現(xiàn)的。
This interferometer used grating as its shearing part. It has characteristics of simple light route, compact structure, low shockproof.
該儀器利用光柵作為錯(cuò)位元件，具有光路簡單，結(jié)構(gòu)緊湊，波像差小，防震要求低等特點(diǎn)。
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.
利用雙頻光柵剪切干涉法，CCD攝像機(jī)采集剪切干涉條紋圖，用自行設(shè)計(jì)的軟件對(duì)圖像進(jìn)行處理，可定量測量光場的時(shí)空相干性以及梯度折射率透鏡的像。
