Abstract
The present invention provides a method for spectroscopic imaging by illuminating a sample with a short infrared pulse, directing one or more probe beams to the sample, and measuring light that is reflected, transmitted, or re-emitted inelastically, where a spectrum is collocated by varying the wavelength of the infrared pulse and an image is collected by moving the sample and probe beam relative to each other as the steps are repeated multiple times to create a multidimensional spectroscopic image of the sample. Also disclosed are the related methods for analyzing the data and the related system for spectroscopic imaging.
