Abstract
The work is concentrated on an experimental approach to determine surface waviness of metal and height of liquid surface wave. It is based on illuminated those surfaces with a highly coherent light such as laser, and observed movement of center of speckle pattern which were gained from the movement surfaces by using tracking program. The movements of the speckle pattern work on carries important information about those surfaces. Two triangulation methods employed to evaluate metal waviness and liquid surface wave. The first method apply on a solid material (metal) and taking a video directly from the reflected surface, the second method apply on the liquid material (oil ) and taking a video after reflected from screen. The methods used here have a great potential for precise and non-contact optical measurements for surface wave measurements.
