A new version of stimulated Raman scattering (SRS) microscopy speeds up image acquisition by allowing multiple bands to be measured simultaneously (J. Am. Chem. Soc., DOI: 10.1021/ja210081h). Dan Fu, Xiaoliang Sunney Xie, and coworkers at Harvard University and the University of Notre Dame achieve the multiplexing by adding an acousto-optic tunable filter (AOTF) to their SRS setup. In the AOTF, acoustic waves sent . . .
