Abstract:
1. A multi-spectral imaging system for inspecting a surface of a manufactured mechanical component, comprising: comprising: a first light source that directs a first beam light having a first wavelength onto the surface; a second light source that directs a second beam of light having a second wavelength different from said first wavelength onto the surface; a camera having a lens, a beam splitter downstream of the lens and a pair of sensors downstream of said beam splitter, said beam splitter passing the first beam of light through said beam splitter and reflecting the second beam of light off said beam splitter, and first one of said pair of sensors being receiving said first beam of light from said first light source to produce one image and a second one of said pair of sensors receiving said second beam of light from said second light source to produce another image different from said one image; a transfer device that moves the component while the first and second beams of light reflect off the surface being inspected; and wherein at least one of said sensors moves toward and away from said beam splitter.
