Improved Version of Solid State Night Vision Sensor

ABSTRACT:The critical, limiting factor for night vision goggles (NVGs) is the sensor. Existing sensor technology for head-mounted systems do not provide the same performance, especially in low light conditions, compared to the latest image intensification technology. However, existing image-intensifier-based NVGs are limited by their size, weight, and cost of the image intensifier tube. This approach also provides imaging of a limited spectral range. Cyan Systems, an innovator in advanced imaging sensor technology, has a wealth of experience in producing cutting edge readout integrated circuits (ROIC), a critical hardware component of many imaging systems. Based on proven technology, Cyan Systems proposes to develop a unique small pixel digital output ROIC that will be hybridized to a high performance visible-NIR-SWIR detector array using advanced small pixel interconnect technology resulting in an ultrahigh definition (UHD) focal plane array (FPA) with superior low noise performance, even at very low light levels, compared to the latest image intensification technology. The digital output FPA will enable multiple system enhancements such as symbology overlay and image processing in a compact camera system that will provide a broader spectral response compared to existing image intensifier tube technology.BENEFIT:The unique small pixel, high sensitivity solid state night vision sensor will permit high resolution, low light level imaging performance for a new generation of head-mounted digital night-vision technology.
