Abstract
In this paper we focus on a new development of an ultrasonic array for endoscopic application in medicine and NDT. This new device is a so-called circular array and consists of more than 80 strip elements. The diameter of this array is 10 mm. The frequency is about 5.0 MHz. The mathematical algorithm, monochromatic and broadband calculations of the soundfield are shown. Furthermore the process of manufacturing is discussed and partially depicted.
