The infrared thermographical improved to impact by progressive accumulation of the lines of the image.

摘要

The system of thermography comprises an infrared camera 1 provided with devices of the scan line and frame and of at least one photosensitive sensor, an electronic processing module, 1984, the signal 2 and the display means of the signal processed 3 on the screen 4 of a television monitor. According to the invention, a control member 17 can cause the slowing of the scanning field in the camera in a ratio n, and, simultaneously, causing a particular treatment of the signal, in the module 2, which consists in adding to the means of an adder 13 and a memory 14, the n signals relating to each field elementary and which are provided at the rate of the scanning of the line, to be in the image memory 15 the result obtained for each field elementary, the image of the field of vision due to impact and improved recovered on the screen 4 of the monitor of television by repetitive reading of the image memory 15. / p & & p & application: treatment of the signal in the infrared thermographical.
