摘要
光学密度是评价光学影像材料的具有唯一性的指标。 随着高分子影像等的发展, 对光学密度的光谱特性的要求也逐渐提高。 2001年ISO对光学密度的测量条件作了新的修改规定。 按照ISO新标准的光谱特性要求设计了新国家光学透射密度基准装置的组件结构, 提出了一种基于光谱特性的光学密度理论测量方案, 并进行了实验研究, 将光学密度的光谱不确定度提高到0.001 1(0
Abstract
tVisual density is an important index for the estimation of photographic film and visual photo. The development of biomedical image and macromolecule image needs high measurement uncertainty of visual density in spectrum characteristic. The ISO standard of visual density measurement conditions was modified in 2001. A series of equipments designed for densitometer enhance the spectral matching between the national standard densitometer and the ISO standard function. And a new measurement formula is given based on theory analysis. According to the measurement data and uncertainty analysis, the combined uncertainties are 0.001 1 (0
