Final Remarks

There are many critical challenges for future civilian and military infrared detector applications. For many systems, such as night-vision goggles, the IR image is viewed by the human eye, which can discern resolution improvements only up to about one megapixel, roughly the same resolution as high-denition television. Most high-volume applications can be completely satised with a format of 1280 × 1024. Although wide-area surveillance and astronomy applications could make use of larger formats, funding limits may prevent the exponential growth that was seen in past decades.
