Abstract

PURPOSE:To detect the size and shape of a defect at a high accuracy by the addition of a reflected wave signal corresponding to the sum of the distance to a microscopic area from transmission vibrators and the distance to the vibrators receiving reflected waves from the microscopic area. CONSTITUTION:Any vibrator 102-n is selected with a selection circuit 103 to apply a pulse thereto from a high voltage pulse generation circuit 106, an ultrasonic beam in an object 112 to be inspected is transmitted in a conical shape and reflected waves from a defect 116 received with other vibrators 102-1. A reflected wave signal is amplified sequentially with an amplification circuit 110 through a scanner 107 and memorized into a memory circuit 111. In a signal treatment circuit 113, the sum is determined between the distance to the microscropic area A set as desired from the vibrator 102-n and the distance to vibrators 102-n... from the microscopic area A and relfected wave signal within a gate period G corresponding thereto are extracted from a memory circuit 111 to be added. The microscopic area A is set sequentially for the entire flaw detection range and a similar signal processing is done to prepare an image signal.
