Abstract:
1. A three dimensional imaging system comprising: a first laser configured to emit light at a first wavelength; a second laser configured to emit light at a second wavelength being different from said first wavelength; means for incrementally increasing an intensity of said first wavelength of light emitted by said first laser; means for scanning said laser light from said first and second lasers onto a target; a photodetector configured to receive and to be responsive to said first wavelength of light reflected from the target, said photodetector further configured to output a respective signal representing each of a plurality (N) of vein images, based on said received light, by differential absorption of said first wavelength, each of said plurality of vein images corresponding to an incrementally distinct depth beneath the target, formed by said incrementally increasing intensity of said first wavelength of light; means for image processing configured to successively layer said plurality of vein images according to said incrementally distinct depth to create a processed vein image, said means for image processing further configured to transmit said processed vein image as a signal to said second laser; said second laser and said means for scanning configured to project said processed vein image onto the target.
