We report a simple add-on for broadband stimulated Raman scattering (SRS) microscopes to enable fast and programmable spectroscopy acquisition. It comprises a conventional dispersive spectrometer layout incorporating a fast digital micromirror device (DMD). The approach is validated by acquiring SRS spectra of standard chemicals. We demonstrate a DMD's advantage in broadband SRS by showing higher signal-to-noise ratio using a multiplexed Hadamard spectral basis and compressive sensing detection. Our results apply to a variety of frequency-domain pump-probe spectroscopy.
我们报告了一种用于宽带受激拉曼散射（SRS）显微镜的简单附加装置，以实现快速且可编程的光谱采集。它包括一个采用快速数字微镜器件（DMD）的传统色散光谱仪布局。通过获取标准化学品的SRS光谱验证了该方法。我们通过使用多路复用哈达玛光谱基和压缩传感检测展示出更高的信噪比，证明了DMD在宽带SRS中的优势。我们的结果适用于各种频域泵浦 - 探测光谱学。
