光谱受激拉曼散射 (SRS) 显微镜的一种简单方法是测量来自光子晶体光纤 (PCF) 的白色探测光的扫描增益/损耗光谱。然而，白光噪声的强度对于 SRS 显微镜来说是一个严重的问题。在这项研究中，我们通过修改自动平衡方案，通过适用于光谱学的平衡检测，展示了带有 PCF 的同步双波长 SRS 显微镜。所开发的自动平衡检测系统可抑制样本引起的噪声消除性能下降，并且适用于具有简单而坚固的光学器件的光谱SRS成像。
A straightforward method for spectral stimulated Raman scattering (SRS) microscopy is to measure the scanned gain/loss spectrum of a white probe light from a photonic crystal fibre (PCF). However, the intensity of the white light noise is a serious problem for SRS microscopy. In this study, we have demonstrated simultaneous two-wavelength SRS microscopy with PCF through balanced detection suitable for spectroscopy with a modification of an auto-balance scheme. The developed auto-balance detection system suppresses the degradation of noise cancellation performance caused by a sample, and is suitable for spectral SRS imaging with simple and robust optics.
