An imaging system that includes a digital micromirror device (DMD) and a tunable filter, wherein the imagining system applicable for Raman imaging, can fluorescent imaging, phosphorescent imaging, photoluminescent imaging, all of which require excitation of a specimen at a particular wavelength and analyzing the reflected light from the specimen at a wavelength that is different from the excitation wavelength, so called inelastic light scattering&#x2014;ILS. A reconfigurable DMD-based inverse, spatially offset Raman spectroscopy (SORS) system is also described. Beneficially, the DMD system in the excitation path provides a uniform intensity over the sample field of view. It is also configured to prevent sample damage. Placement of a second DMD in the return path of light enables selective rejection of light in space to obtain a reconfigurable inverse SORS system that enables collection of information from different layer depths of the sample using a single detector.
