Evaluation of Surface Roughness Using Interferometry – A Review
Keywords:Speckle, White light, Digital holography, Laser techniques applications
In this article we present a review of various method of interferometry principle for assessment of surface roughness. Techniques such as speckle, white light interferometry, digital holography, laser optical systems, microscopic shear and optical profiler have been presented. Images were captured by CCD and machine vision systems are used to carry out morphological operations and to perform analysis and for finding out surface roughness.
