1. a kind of based on the colour imaging temperature field measuring apparatus for aiding in frequency modulation light source, it is characterised in that including:

  • Auxiliary modulating lightSource and coloured image photoelectric sensor;

    The auxiliary frequency modulation light source is used for irradiation object under test surface in the on state;

    The coloured image photoelectric sensor is used under the auxiliary frequency modulation light source opening, gathers the determinand body surfaceFirst coloured image in face;

    Wherein, the red, green, blue chromatic value of each pixel of first coloured image corresponds to three respectivelyFirst radiation intensity of spectrum channel;

    The coloured image photoelectric sensor is additionally operable under the auxiliary frequency modulation light source closed mode, gathers the object under testSecond coloured image on surface;

    Wherein, the red, green, blue chromatic value of each pixel of second coloured image corresponds to three respectivelySecond radiation intensity of individual spectrum channel;

    Wherein, each position on each pixel of first coloured image and the second coloured image and object under test surface is one by oneCorrespondence;

    The temperature of the specified location of the object under test is that first radiation of any spectrum channel according to respective pixel is strongThe radiation intensity of itself determines in the on state for degree, the second radiation intensity and the auxiliary frequency modulation light source.
