Background technology
Spoke brightness has consequence as a fundamental physical quantity in the radiometry in the optical metrology field.According to the difference of first grade standard, spoke brightness calibration can be divided into two classes: based on calibrated radiation source with based on standard detector.NIST once did two kinds of method spoke brightness calibration results' comparison, and its consistance has reached in 0.5%.Be accompanied by low temperature radiometer and standard detector based on the detector calibration method and grow up, the standard transfer chain has been shortened in its appearance.The measuring accuracy of low temperature absolute radiometer also is known as the highest at present in addition.Therefore, the spoke brightness calibrating method based on detector has more high precision than the calibrating method based on radiation source.
Two kinds of spoke brightness calibrating methods introducing above have several common ground: grade standard at the beginning of, all having is a gold-point blackbody based on the first grade standard of radiation source method, and based on the detector method is low temperature radiometer.The precision of these two kinds of elementary standard sources directly has decisive influence to the calibration precision of back.Two, all need the standard transfer chain, first grade standard carries out transmission step by step.The introducing of every grade of transfer chain all can make the uncertainty of transmission increase.In addition, in the measuring method based on detector, also need aperture area is measured, this step also inevitably can be brought uncertainty.Therefore, from the 60 to 70's of twentieth century, just begin to set up a kind of absolute calibration method that does not rely on first grade standard and transfer chain.The ultimate principle of this method also is in the middle of the active research at present along with conversion under the parameter constantly grows up in the optical radiation measurement Application for Field.
