Claim 16:
17. A method of operating a system for simultaneously characterizing infrared absorption characteristics of a plurality of locations on a sample, the method comprising the steps of:
illuminating the plurality of locations of the sample with a source of infrared radiation to create an infrared illuminated spot on the sample;
illuminating the plurality of locations of the sample with a source of probe radiation;
collecting probe radiation from the plurality of sample locations;
detecting collected probe radiation with at least one camera; and
analyzing camera detected probe radiation to generate signals indicative of infrared absorption of the plurality of locations on the sample, wherein the signals indicative of infrared absorption of the plurality of sample locations achieve a spatial resolution of less than 1 μm.
