此外,他们还担心“天空回散照射(sky shine)”的问题:房顶散发的辐射会被大气中的颗粒向下反射。
They were also concerned about “sky shine”: radiation emanating from the roof that’s reflected downward by atmospheric particles.
激光经过被测表面反射和散射后,通过自由空间传播至观察面上形成散斑图像,其统计分布依赖于被测表面的微观形貌。
Speckle images are produced by the reflected and scattered light beams from rough surface through free-space to observing plane when laser illuminates the object surface.
本文最后提出了旨在提高测量灵敏度的二种实验技术-反射式激光散斑照相法与附加位移法。
Finally, two experimental techniques -the reflective laser speckle photography and the image shift are presented to improve the measurement sensitivity.
