speckle shearing interferometry

基本解釋

Both theory and experiments show that stroboscopic shearing speckle interferometry is obviously superior to time-average method.
理論和實(shí)騐都表明頻閃剪切散斑乾涉照相法要優(yōu)於時(shí)間平均剪切散斑乾涉照相法。
A kind of enciroled-circular double wedge (E-CDW), in which shearing amount could be varied continually, is recommended for speckle shearing interferometry.
本文提出一種錯(cuò)位量連續(xù)可調(diào)的圓一環(huán)雙光楔作爲(wèi)錯(cuò)位乾涉元件進(jìn)行激斑照相。
Speckle-Shearing Interferometry is a kind of method that directly measures surface full-field strain. It does not need to differentiate with respect to the measured displacement to obtain the strain.
散斑剪切乾涉法是一種直接測(cè)量表麪全場(chǎng)應(yīng)變的方法，它取消了由測(cè)定位移而計(jì)算微分的要求。
