FIELD: physics.SUBSTANCE: laser-spectrometer-computer metre of light flux and quantities changing said light flux (in short: "lascomtel") comprising a laser, a spectrometer, a system of light cables and a computer is used. The lascomtel is calibrated in advance, while storing in computer memory electronic temperature calibration curves with calibration conditions thereof, e.g., in form of a family of calibration curves. Before measuring, the lascomtel is switched on and adjusted. Measurements start with turning off the laser; the cable end is directed onto the measured point; temperature light flux passes through the spectrometer from the measuring point; the computer displays a spectrometer graph with a spectrometer curve and at the instruction of the measuring computer, superimposes the family of calibration curves onto said curve; temperature of the object is determined from the position of the spectrometer curve relative the closest curves of the family of calibration curves. In order to determine coordinates of the measuring point or direct the inlet cone onto the measured point, the laser is switched on. The centre of the larger base of the outlet cone of the laser is taken as the measuring point.EFFECT: high accuracy of measuring temperature even of inaccessible places in less than minute.11 cl |
