Raman spectroscopy using spatial light modulators

Due to the high flexibility and throughput, Spatial Light Modulator (SLMs) have been widely used in optical microscopy and spectroscopy for various applications. In this talk, I will present some example applications of Raman spectroscopy using two types of SLM, LC-LSM (liquid crystal-spatial light modulator) and DMD (digital micromirror device). Several modalities of Raman spectroscopy can be achieved by using LC-LSM and/or DMD, such as multi-foci Raman spectroscopy and spatially offset Raman spectroscopy (SORS). The SLMs allow the system to be flexible and efficient in collecting Raman signal, requiring no changes to the optical system or mechanical adjustment.
