Abstract
The quarter megabuck cost of VGA-resolution infrared focal plane array cameras is sufficient grounds to look at alternative designs for high-speed infrared imaging systems. In addition, one has to deal with flawed sensors. Using linear models and linear thinking, the state of the technology in optical design has apparently crested. The existence of 6.5-to-1 lossless image compression for infrared is sufficient to establish that sufficient redundancy exists to reconstruct the flawed data. We are convinced that most real-time imaging systems could be improved with real-time morphological coprocessing. By building in additional redundancy using a 768 X 3 linear infrared sensor, we have designed an infrared camera system with a single rotating mirror which produces better pictures than existing focal plane array systems with comparable data rates to the existing focal-plane array systems, and one tenth the electronics of existing focal-plane array systems. Flaws are removed by morphological processing, converting redundant linear scans of the 768 X 3 sensor to a 768 X 1 linear array. As the mirror turns, a full 2-D image is recovered, producing a super-VGA (1024 X 768) resolution image.
