Many imaging sensors, and display technologies can benefit from RGB-NIR light sources. Under low light conditions, for example, high levels of noise and motion blurring can appear in images captured using conventional cameras and white flash lamps. An RGB-NIR imaging system capable of using simultaneously the red, green, blue (RGB) along with NIR can help mitigate the effects of heavy noise and blur.
Since it is particularly useful for low lighting conditions, NIR imaging is employed heavily in surveillance and night vision cameras. The NIR band is also used in biometric and face recognition applications, as well as various photo enhancement applications such as image dehazing.
Our advanced and proprietary phosphor technology can produce RGB-NIR LED sources without the need for fabrication and use of separate visible and infrared LEDs. They can be built into or added to a single compact source of light or camera flash (as remote phosphors) and transform it into an emitter capable of delivering high brightness RGB-NIR illumination at low cost and with high visible color rendition. The RGB and NIR ratios can be customized for a particular sensor application or device.
