Multispectral detection and presentation of an object's characteristics
First Claim
1. An apparatus for capturing a multispectral image of an object comprising one or more means for transmitting a beam of laser light at a first wavelength and a beam of laser light at one or more additional wavelengths different from the first wavelength, a means for causing said beams of laser light to travel in a coaxial path and a moving mirror wherein said beams of light bounce off said mirror thereby producing a two dimensional projection pattern, said pattern travelling from said mirror along a first path to an object and wherein some of the laser light penetrates said object and travels to an internal structure and wherein reflection of the laser light returns to a photo detector along a path different from said first path.

Abstract
An apparatus for capturing a multispectral image of an object is described. The apparatus includes one or more means for transmitting a beam of laser light at a first wavelength and a beam of laser light at one or more additional wavelengths different from the first wavelength. There is a means for causing the beams of laser light to travel in a coaxial path and a moving mirror. The beams of light bounce off the mirror thereby producing a two dimensional projection pattern. This pattern travels from the mirror along a first path to an object and wherein some of the laser light penetrates the object and travels to an internal structure of the object. The reflection of the laser light returns to a photo detector along a path different from said first path.
