Abstract
This paper presents a computer application of the surface roughness measurement of highly smooth surfaces. The Phase Shifting Interferometry technique which is a non-contact technique is applied for the roughness measurement. Our optic-based measurement system utilizes a 0.5 mW He-Ne laser source with the wavelength of 632.8 nm. Fringes from the measurement system were recorded using a high precision camera and were analyzed by our programs to produce the surface roughness measurement. This technique is a simple technique which gives accurate results. It is a four-frame algorithm giving similar results to the more complex five-frame one with less processing time.
