The invention concerns a radiation pyrometer of the thermo camera type, by which the thermal radiation of the object under investigation is changed into a video signal by being fed to a television camera (5) via an optical system (1). The video signal is conducted partly to a television monitor (6) and partly to a stage (8) for sampling and measuring the video signal's amplitude.Marks, in the form of movable spots of light on the monitor's (6) screen, indicate the place on the object for temperature measurement, and are generated by a marker unit (7), which controls stage (8). An initial coupler (4) for optical filtering successively transfers the spectral components in the radiation from the object in at least two different spectral regions. A second coupler (9) receives information from stage (8) and signals from the initial coupler (4) in order to separately derive information about the different spectral components' densities. This is conducted to a computer (10) for processing. The processed information is displayed on the monitor's (6) screen.<IMAGE> |
