1. A quantum theory correction method for improving accuracy of a radiation thermometer system, the said method comprising following procedures:

  • (1) Measure a standard temperature Ti of a object by using standard temperature measurement instrumentation;

    measure the thermal radiation signal voltage Ui(Ti) of the object, where i=1, 2, 3, 4 . . . N and N is a positive integer, by using the radiation thermometer system at a calibration state;

    input the said standard temperature Ti and the said thermal radiation signal voltage Ui(Ti) into a PC or MCU radiation for data processing to acquire parameters reflecting energy level structure;

    using a said physical model includes;



    is used in the case of the radiation thermometer system with narrow working band;

    after working band is selected suitably, the model is simplified as U(T)=A(eB/T) if the working band is short wave; and

    U(T)=AT+B if the working band is long wave;

    the parameters A and B reflecting energy level structure are obtained by inputting data into the physical model and fitting it with least square method;
