摘要：

This paper deals with the optimization of curved high frequency annular arrays for use in ultrasonic microscopes. Sound field calculations were made for water, and solids after a water delay. In contrast to linear element arrays, annular arrays can work effectively with only a small number of large transducer elements without the risk of getting side lobes. The results show that curved sparse arrays with 10 elements and a centre frequency of 35 MHz work fine in fluids. With only half the number of elements, sparse arrays achieve the same resolution of about 60 Pin as a full array of the same aperture. In steel, a resolution of I 10 gm is achievable with a curved full array of only 20 elements.
