Abstract
Abstract A camera system for simultaneously recording separate near-infrared and visible light images is disclosed having a visible light source for illuminating a given area with visible white light, indicia generating means for directing an image of a wavelength of light longer than wavelengths of light of the visible white light upon the given area, a first electronic camera for recording an image of the visible light but not the longer wavelength of light and a second electronic camera for recording an image of the longer wavelength of light but not the visible light, and a single cold mirror common to the two cameras for directing the two light images to their respective cameras.
