Claims
- 1. A camera system for simultaneously recording separate near-infrared and visible light images comprising:
- (a) visible light source means for illuminating a given area with visible white light;
- (b) indicia generating means for directing a light stripe image of a wavelength of light longer than wavelengths of light of the visible white light upon said given area, the image having an area substantially smaller than said given area;
- (c) first camera means for recording an image of said visible light but not said longer wavelength of light;
- (d) second camera means for recording an image of said longer wavelength of light but not said visible light;
- (e) a first optical system for transmitting said visible light but not said longer wavelength of light from said given area to said first camera means;
- (f) a second optical system for transmitting said longer wavelengths of light but not said visible light to said second camera means; and
- (g) mirror means positioned within said first and second optical system and between said given area and both said first and second camera means, said mirror means being configured to reflect said visible light and transmit said longer wavelengths of light through said mirror means to said second camera means.
- 2. The camera system of claim 1 wherein said visible light source means comprises a lamp which generates some infra-red radiation, and further including a short-pass filter for blocking transmission of the infra-red radiation to said given area.
- 3. The camera system of claim 2 wherein said visible light source means includes a quartz-halogen lamp.
- 4. The camera system of claim 3 wherein said first and second camera means comprise electronic image sensors.
- 5. The camera system of claim 2 wherein said first and second camera means comprise electronic image sensors.
- 6. The camera system of claim 1 wherein said first and second camera means comprise electronic image sensors.
- 7. A camera system for simultaneously recording separate near-infrared and visible light images comprising:
- (a) visible light source means for illuminating a given area with visible white light;
- (b) indicia generating means for directing a light stripe image of a wavelength of light longer than wavelengths of light of the visible white light upon said given area, the image having an area substantially smaller than said given area;
- (c) first camera means for recording an image of said visible light but not said longer wavelength of light;
- (d) second camera means for recording an image of said longer wavelength of light but not said visible light;
- (e) a first optical system for transmitting said visible light but not said longer wavelength of light from said given area to said first camera means;
- (f) a second optical system for transmitting said longer wavelengths of light but not said visible light to said second camera means; and
- (g) means for positioning a wavelength responsive optical component within said first and second optical system and between said given area and both said first and second camera means, said wavelength responsive optical component being configured to reflect said visible light and transmit said longer wavelengths of light through said mirror means to said second camera means.
- 8. The camera system of claim 7 wherein said visible light source means comprises a lamp which generates some infra-red radiation, and further including a short-pass filter for blocking transmission of the infra-red radiation to said given area.
- 9. The camera system of claim 8 wherein said visible light source means includes a quartz-halogen lamp.
- 10. The camera system of claim 9 wherein said first and second camera means comprise electronic image sensors.
- 11. The camera system of claim 8 wherein said first and second camera means comprise electronic image sensors.
- 12. The camera system of claim 7 wherein said first and second camera means comprise electronic image sensors.
- 13. A camera system for simultaneously recording separate near-infrared and visible light images comprising:
- (a) visible light source means for illuminating a given area with visible white light;
- (b) indicia generating means for directing at least one narrow elongated image of a wavelength of light longer than wavelengths of light of the visible white light upon said given area;
- (c) first camera means for recording an image of said visible light but not said longer wavelength of light;
- (d) second camera means for recording an image of said longer wavelength of light but not said visible light;
- (e) a first optical system for transmitting said visible light but not said longer wavelength of light from said given area to said first camera means; and
- (f) a second optical system for transmitting said longer wavelengths of light but not said visible light to said second camera means, simultaneously with transmission of said visible light to said first camera means.
- 14. The camera system of claim 13 wherein said visible light source means comprises a lamp which generates some infra-red radiation, and further including a short-pass filter for blocking transmission of the infra-red radiation to said given area.
- 15. The camera system of claim 14 wherein said visible light source means includes a quartz-halogen lamp.
- 16. The camera system of claim 15 wherein said first and second camera means comprise electronic image sensors.
- 17. The camera system of claim 14 wherein said first and second camera means comprise electronic image sensors.
- 18. The camera system of claim 13 wherein said first and second camera means comprise electronic image sensors.
