Abstract
There are two general methods for radiometric calibration of detectors. One is based on radiometric sources and the other is based on detectors. Because two methods need to establish primary standard of high precision and transfer chain of standard, the precision of standard will be reduced by extension of the chain. An absolute calibration of quantum efficiency of detectors can be realized by using correlated photons generated in spontaneous parametric down-conversion (SPDC) effect of nonlinear crystal. Generation mechanism of SPDC is interpreted with theories of quantum mechanics and classical theories. The theory of calibration based correlated photons are demonstrated. The project for proof of principle of absolute calibration of quantum efficiency of radiometric detectors is given in this paper. Comparing with traditional methods, the advantages of it are pointed out. A scheme using to calibrate quantum efficiency of infrared detectors is described here. The measurement of spatial and spectral response of detectors is mentioned too.
