Abstract
A night vision apparatus and method comprising employing a detector operating in the 7 to 14 microns wavelength region, converting via electronics and/or photonics the received light to the region visible to the human eye, and displaying the visible light on a display, wherein a housing contains the detector, the electronics and/or photonics, and the display.
Claims20
Night vision apparatus comprising:
- a detector operating in the 7 to 14 microns wavelength region;
- electronics and/or photonics converting the received light to the region visible to the human eye;
- a display displaying the visible light;
- an optical limiter;
- an electrical limiter that protects the human eye so that sudden environmental temperature variation displays as a more gradual change;
- and
- a housing containing said detector, said electronics and/or photonics, said optical limiter, said electrical limiter, and said display.
