摘要: 现行测色法多以常规光谱为基础。通过测量样品对光的透射或反射率以及光源的能量分布,叠合色匹配函数,来寻找颜色的三刺激量,由此获取样品的色别、色饱和度和明度的信息。这些方法的共同特点是定向输入光子,并计量定向输出光子的情况。为了能将测定范围扩展到那些高反射、散射、漫射、辐射和层状样品,对一般常规光谱法是困难的。我们因此提出了光声测色法(PAC)。

Abstract: Photoacoustic colorimetry (PAC) was first proposed.It is believed that the unnormalized photoacoustic spectrum can be taken directly by CIE standard colori-metric system to get the dominant wavelength (hue), purity (chroma) and lightness (value), by matching of spectral tristimulus values.Several PAC experiments of Fogra Pms control strips, dyes, color papers, soils, fluorescent and biological materials etc.were made.

Key words: photoacoustic colorimetry, CIE colorimetric system
