This paper presents an experimental scanning measurement system. The system uses ultrasonic waves in a water-coupled medium to scan an immersed object. Pulse-echo mode is enabled, and data are measured at different locations using an automated table (scanner). A microcontroller is used to control the movement of the scanner, whereas a MATLAB code is used to control the operation of the ultrasonic pulser receiver. MATLAB is also used to control the movement of the automated table. Reflected ultrasonic waves are recorded, and an A-scan image of the surface is generated. The experimental results of a one-pound coin show that the proposed measurement method can be used with high accuracy and can be utilized in further applications with minimal errors.
