Abstract
An automated fringes counting system is developed to calculate the wavelength of the light source by Michelson Interferometer via image processing method. The system is designed by National Instruments LabVIEW Programing with help from vision acquisition and image processing module. The Michelson Interferometer is constructed with a beam splitter, an adjustable mirror, and movable mirror and a convex lens with focal length of 18mm. A CCD camera with a resolution of approximately 1.4MP is used to capture the fringes pattern image on the viewing screen. This system using edge detection with checks the difference in pixel intensity of the both ends on the line ROI greater than threshold value or contrast in range of 11 to 15 in dark room condition. The most accurate results is 640.00nm with error of 1.14% for N = 150.
