光谱光学相干断层扫描（OCT），传统的OCT的扩展，被证明用于执行横截面断层扫描和光谱成像。通过检测和处理干涉OCT信号获得关于后向散射光的光谱内容的信息。该方法允许在单次测量中同时在整个可用光学带宽上测量后向散射光的光谱。可以通过使用数字信号处理来提取特定的光谱特征，而无需改变测量装置。一个超宽带飞秒Ti：Al2O3激光器被用来实现光谱成像的波长范围从650到1000 nm的一个简单的模型，以及在体内的非洲爪蟾（非洲青蛙）蝌蚪。多维光谱数据显示使用一种新的色调饱和度假彩色映射。(C)2000年美国光学学会。OCIS代码：110.4500、100.6950、100.7410。
Spectroscopic optical coherence tomography (OCT), an extension of conventional OCT, is demonstrated for performing cross-sectional tomographic and spectroscopic imaging. Information on the spectral content of backscattered light is obtained by detection and processing of the interferometric OCT signal. This method allows the spectrum of backscattered light to be measured over the entire available optical bandwidth simultaneously in a single measurement. Specific spectral features can be extracted by use of digital signal processing without changing the measurement apparatus. An ultrabroadband femtosecond Ti:Al2O3 laser was used to achieve spectroscopic imaging over the wavelength range from 650 to 1000 nm in a simple model as well as in vivo in the Xenopus laevis (African frog) tadpole. Multidimensional spectroscopic data are displayed by use of a novel hue-saturation false-color mapping. (C) 2000 Optical Society of America. OCIS codes: 110.4500, 100.6950, 100.7410.
