最近开发的非线性光学泵浦-探测显微镜技术使用调制转移灵敏地提取激发态动力学的内源性生物色素，如真黑素和褐黑素。在这项工作中，我们使用这种方法来成像和表征历史艺术中使用的几种无机和有机颜料。我们表现出实质性的差异，在近红外泵浦探测签名名义上类似的颜料，并建议扩展到艺术修复。(C)2012美国光学学会
A recently developed nonlinear optical pump-probe microscopy technique uses modulation transfer to sensitively extract excited-state dynamics of endogenous biological pigments, such as eumelanin and pheomelanin. In this work, we use this method to image and characterize several inorganic and organic pigments used in historical art. We show substantial differences in the near-IR pump-probe signatures from nominally similar pigments and suggest extensions to art restoration. (C) 2012 Optical Society of America
