摘要：

This paper describes the design, fabrication, characterization and test of three sectorized array transducers: one for air-coupled operation (400 kHz, 25 mm diameter) and two for water-coupled operation (4 MHz, 10 mm diameter and 2 MHz, 5 mm diameter). The objective is to use these transducers in pulse-echo mode along with a conical reflector to generate a 2D cylindrical acoustic field with angular resolution that can be used for industrial and/or medical ultrasonic endoscopy. Some examples of use of these prototypes to inspect different pipes (size and materials) and to determine both inner diameter and wall thickness are also shown.
