Claim 12:
13. A microscope system of performing infrared imaging of a sample, the microscope system comprising:
an excitation light source configured to illuminate the sample with a beam of excitation radiation to excite autofluorescent emission from the sample;
a camera-based detector arranged to capture at least a portion of the autofluorescent emission from the sample to produce a frame autofluorescent image of the sample;
an infrared light source configured to illuminate at least a portion of the sample corresponding to the frame autofluorescent image with a beam of infrared radiation;
a camera-based detector configured to capture at least a portion of the autofluorescent emission from the sample while the portion of the autofluorescent emission from the sample is perturbed by the infrared light absorbed by the sample to produce the IR-absorbed frame autofluorescent image; and
a processor configured to construct a signal indicative of infrared absorption by the sample using the autofluorescent frame and the autofluorescent IR-absorbed frame.
