This paper describes an experimental setup that employs ultrasound to scan an area. This method utilizes ultrasonic waves to scan the surface of a submerged object in a water-coupled medium. A pulse-echo mode is used, and quantitative data are collected at various positions using a two- dimensional automated table. A microcontroller controls the motion of the scanner, whereas a script developed in MATLAB controls the ultrasonic pulser receiver process. The MATLAB script ultimately controls and correlated between the scanner movement and ultrasonic pulser receiver process. The intensities of the reflected waves are captured and used to generate the A-scan image for the external surface. The surface profile of the scanned object can be clearly obtained using the time arrival of the reflected waves. The experimental results based on a one-pound coin indicate that the precision of the proposed process. This simple and efficient method can be used in different engineering applications with minimum errors.
