A method of an apparatus for tracing a surface temperature profile on the screen of a CRT using an infrared scanning camera system. Horizontal and vertical CRT beam deflection signals are derived from the appropriate scanning elements of the camera and horizontal and vertical beam control signals are produced by superimposing on the horizontal deflection signal and on the sensor signal respectively, a fraction, preferably different fractions, of the vertical deflection signal to produce an apparently three-dimensional display of the temperature profile. <IMAGE> |
