Abstract
A system for generating reflectance values for a target that includes a plurality of electromagnetic radiation sources for irradiating the target, an imager for generating a plurality of digital representations of the target that includes an array of filter elements for filtering electromagnetic radiation reflected by the target through an array of filter elements, and a detector for detecting the filtered electromagnetic radiation at an array of detection elements. The system includes processors for determining a set of reflectance values for a portion of the target based on a first digital representation of the target generated in response to irradiation of the target with radiation of a first wavelength band and a second digital representation of the target generated in response to irradiation of the target with radiation of a second wavelength band.
