Until now, spatially resolved Raman Spectroscopy has required to scan a sample under investigation in a time-consuming step-by-step procedure. Here, we present a technique that allows the capture of an entire Raman image with only one single exposure. The Raman scattering arising from the sample was collected with a fiber-coupled high-performance astronomy spectrograph. The probe head consisting of an array of 20 × 20 multimode fibers was linked to the camera port of a microscope. To demonstrate the high potential of this new concept, Raman images of reference samples were recorded. Entire chemical maps were received without the need for a scanning procedure.
到目前为止，空间分辨拉曼光谱需要在一个耗时的逐步过程中对被研究的样品进行扫描。在此，我们提出一种技术，该技术仅通过一次单次曝光就能捕获完整的拉曼图像。用光纤耦合的高性能天文光谱仪收集样品产生的拉曼散射。由20×20多模光纤阵列组成的探头连接到显微镜的相机端口。为了证明这一新概念的巨大潜力，记录了参考样品的拉曼图像。无需扫描程序即可获得完整的化学图谱。
