复现坎德拉的测试方法研究

RESEARCH ON MEASURING METHOD FOR CANDELA REAPPEARANCE

介绍一种利用低温辐射计算复现坎德拉的新方法 ,并把它与电校准绝对辐射计法进行了比较。该方法用低温辐射计测出滤光辐射计的绝对光谱响应 ,从而使坎德拉的复现成为可能。

A new method, which reappears candela with cryogenic radiometer and makes comparison with the method of electric calibrated absolute radiometer, is introduced. The new method is that the absolute spectral response of filter radiometer is measured with cryogenic radiometer, so that makes it possible to reappear candela.
