计算机Moire偏度法测量液体折射率

Measurement of the Refractive Index Using the Computer Moire Deflectometry

提出一种基于Talbot效应的实时计算机莫尔偏废法（Computermoiredeflectometry），它是由光栅，CCD摄像机，计算机像处理器（CIP）构成。CIP用来实时获得、测量和处理由透明和反射物体所产生的光学图像。测量精度10-5。

Cornputer moire deflectometry (CMD) using two gratings, a CCD camera and a cornputer image processor(CIP) is developed. G, grating locates in a Talbot plane. Moire pattern in CMD is obtained with maximum contrast. CIP is used for obtaining, processing and measuring fringes for transparent and reflective object, with accuracy 10-5.
