Abstract:
1. An imaging system for imaging a subsurface region of interest, comprising: a plurality of coherent light sources; an optical assembly that spatially scans respective outputs from said plurality of coherent light sources onto a surface of the region of interest; a first coherent light source providing light of a first wavelength of the electromagnetic spectrum that penetrates the surface to interact with a first kind of structure beneath said surface, a portion of said light at said first wavelength then returning to a detector of said light of said first wavelength; a second coherent light source providing infrared light at a second wavelength, longer than said first wavelength, said infrared light also penetrating the surface to interact with a second kind of structure beneath said surface, a portion of said infrared light then returning to a detector of said infrared light; a signal processing unit receiving a first signal corresponding to said returned portion of said first light and a receiving a second signal corresponding to said returned portion of said infrared light, said signal processing unit generating an output indicative of a sensed condition beneath said surface determined at least by both of said first and second signals received corresponding to the returned first light and returned infrared light; and a display light source emitting a visible display signal projected onto said surface of the region of interest corresponding to the sensed condition as a function of position on said surface of the region of interest.
