Abstract
In this work a laser scanning setup was designed and constructed by using Laser speckle technique, in which a linear relationship between Laser speckle Contrast and surface roughness . During the work standard stainless steel rough Surface was been used. From the results it is found that incident angle HAS a great influence on the measurements and this due to the saturation phenomena. For Incident angle (15°) saturation takes place with(R=0.12 μm) AND for more roughness the contrast decreased .When the incident angel become (30°) the contrast saturated at ( R= 0.12 μm) and stay constant for more roughness . At angle (75°) saturation in CONTRAST TAKES place at(R=0.4μm) and the value of contrast less than that of 15° and 30° angles.
