Abstract
PURPOSE:To measure a temperature pattern with high accuracy without any influence of the circumference by employing two-color thermometer technics and a picture information processing technics. CONSTITUTION:A collection of optical fiber is used as an image guide 1. An objective end and another end thereof are connected with a welded portion at right angle and an imge photograph apparatus 2 respectively. A video signal VDS output by the image photograph apparatus 2 outputs to a video signal treatment circuit 5 which works the video signal for data treatment together with outputting to a CRT4 for monitor. The video signal treatment circuit 5 feeds a picture signal in the video signal VDS input therein to an arithmetic unit 6. The arithmetic unit 6 consisting of a small type of computer calculates a temperature in each area in turn and obtains a whole temperature pattern of a photographed picture, thereby indicating or recording it with a display, plotter, or the like. Thus, the temperature pattern can be measured with high accuracy without being affected by a surrounding atmosphere.
