1. An apparatus for noninvasive evaluation of a target versus a non-target, comprising: one or more light sources having at least one emission spectra directed at less than the entire target wherein the one or more light sources are configured to not contact the target; two or more detectors positioned to capture light reflected from the target into two or more spatial images of the target at two or more times without contacting the target; and a processor for receiving the two or more spatial images, wherein the one or more light sources are positioned to minimize near-surface reflectance incident on the detectors, and wherein the processor further performs a transform analysis of time variations of at least a portion of the spatial images to distinguish between target and non-target image information.
