Analog signals representing infrared radiation from an object are generated by a scanner. These signals are digitized and one frame of data is stored in a computer. The computer and a display generator process the data, and supply one frame to a TV monitor which displays an image of the object. A grey scale is also displayed alongside the image to provide calibrated quantitative information related to the temperature at different places of the object. A tape recorder may be used to record the analog signals, for later digitizing and displaying the images. |
