Abstract

PURPOSE:To freely move a probe and perform flaw detection operation easily and rapidly by detecting the position of the probe with a telecamera. CONSTITUTION:In case a probe P is placed on the subject S to be examined and is started, a mark L is projected on the screen of an image receiver B in the position opposing to the probe P. When it reaches the position where there is a defect, a defect echo pulse is transmitted from a flaw detector Q, and the intensity thereof is recorded in a memory device M. The gain of an amplifier G rises and the input corresponding to the size of the defect is applied to the image receiver B, then the luminance of the image of the mark L increases according to the size of the defect. When the entire surface of the subject S is scanned with the probe P, the signals corresponding to the sizes of the defects are stored in the addresses corresponding to the defect positions in a memory device M. If the signals of the memory device M are read out successively, the sizes of the defects are indicated as changes in brightness in the positions corresponding to the addresses having been stored on the two-dimensional plane formed by the screen.
