微位移测量仪 meaning in English

micro displacement meter

The main idea of this research can be summed up as following words , reflecting light or scattering light upon the surface of measured object formats an image on the photo surface of psd by a optical system , because of the good relationship between the offset of image point in psd and the offset of object thickness , a mathematical model can be founded according to this relationship . it can measure the shift of object thickness through these analyses of movement of image point position in psd , and this device can be tested its reliability with many practical specimens
光学式非接触厚度-微位移测量仪是在激光三角测量法的基础上实现的，在本研究方案中，根据象点在psd上的移动量建立与被测物厚度-微位移变化之间的数学模型，通过对象点位置变化的计算，实现被测物厚度-微位移变化量的测量。本文重点阐述了光学式非接触厚度-微位移测量仪的工作原理，并对测量仪的工作过程进行了分析；对影响测量精度的因素做了讨论。
