本文从彩色摄影需要出发,依据美国ANSI彩色标准,研究了摄影物镜的光谱透射率及其彩色还原问题。
According to the American colour standard ANSI, the spectral transmittance and colour restoration of photographic lenses are investigated in this paper.
通过国家标准测微尺标定后,每次测试只须选择与物镜相对应的比例尺数值即可直接得到样品的实际大小数值。
Adopted national standards micrometer scale calibration, it can get the actual numerical size after selecting the numerical scale that corresponding to objective lens in each test.
