近年来,国内已相继研制成功各具特色的自动光谱辐射计。我们应上海灯具厂的要求,研制成功了“分光型光源测色仪”。该仪器采用光谱光度法,将被测信号灯所包含的光谱成分用单色器分解出来,然后测定其相对光谱功率分布,并通过一系列的数据处理,求得色品坐标值。现将该仪器的测色原理及结构作一简要介绍。 In recent years, China has successfully developed its own unique automatic spectral radiometer. We should be the requirements of Shanghai Lighting Factory, developed a successful “spectrophotometer light color measurement instrument.” The instrument uses spectrophotometry, the signal components contained in the measured spectral components with a monochromator decomposition, and then determine the relative spectral power distribution, and through a series of data processing, color coordinates obtained. Now the instrument’s color measurement principle and structure for a brief introduction.
