Abstract
A system and method for mapping a tissue sample is provided. The system includes a light source, a scanner, a digital mirror device (DMD), a light detector, and an analyzer. The DMD has an array of micromirrors. The analyzer controls the light source, controls the scanner, controls the DMD to have on-state micromirrors aligned with a light beam, and other micromirrors in an off-state. The on-state micromirrors direct the light beam to a tissue sample. The analyzer assigns one or more location codes to the on-state micromirrors, controls the light detector to receive Raman light emitted from the tissue sample, correlates the location codes of the on-state micromirrors with light detector signals representative of the Raman emitted light, and produces a spatial map of the Raman emitted light.
