ABSTRACT
This article reports that developers of solid-state lighting systems are also expanding the capabilities of night vision for applications such as automotive safety, infrastructure security, and search and rescue, by extending visible light-emitting diode (LED) and laser technology into the near-IR spectrum. The sensitivity of CMOS and CCD detectors tends to fall off in moving from the visible to the IR. Near-IR illumination sources used to extend the spectral range for night vision include halogen bulbs, IR LEDs, and IR lasers. Halogen bulbs cost the least, but they are only 5% efficient in producing light.
