Claim 20:
21. A system for acquiring data regarding a wound in tissue, comprising:
at least one excitation light source configured to illuminate a target with excitation light and cause bacteria present on and/or in the target to fluoresce;
an optical sensor configured to detect signals responsive to illumination of bacteria on and/or in the target with excitation light, each signal indicative of at least one of endogenous fluorescence, exogenous fluorescence, absorbance, and reflectance in the illuminated target;
a thermal sensor configured to capture thermal data regarding the target; and
a processor configured to receive the detected signals, to identify pixels corresponding to bacterial fluorescence emitted from the target and having an intensity above a predetermined threshold, to calculate bacterial load of the target based on the identified pixels, and to output data regarding the bacterial load of the target.
