Abstract
A method and system for rapid, label free nanoscale chemical imaging and tomography (3D) with multiplexing for speed, and engineered coherent illumination and detection to achieve 3-D resolution at twice the Abbe limit. A sample undergoes photo-thermal heating using a modulated infrared light source and the resulting probe beam modulation is measured with one or more visible laser probes. Varying the infrared wavelength results in a spectrum which characterizes the chemical composition of the sample. Optionally, inelastically scattered light generated as a result of the probe beam interacting with the sample is collected simultaneously to yield additional chemical information.
