PURPOSE:To make possible the analysis of distance or depth using an indicated image by freely moving a fine scale for partial indication while a coarse scale indicates the whole picture. CONSTITUTION:Detection information is obtained with a receiver 15 for each supersonic pulse, undergoes a digital conversion with an AD converter and memorized in the buffer memory 21. The information in the memory 21 is shifted to and stored in the main memory 22, which indicates each detection information on the vertical indication line 25 at the right end of the indication picture 24 of CRT 23. The newest detection infomation is indicated at the right end while the old one moves in order to the left end of the picture. The color CRT is used to change the color according to the level of the input signal shifting from 0 level in blue to the largest in red by degrees. A scale is partially superimposed to indicate the detected distance, depth or the like in greater details, and is made movable by means of a divider. |
