Abstract

A high speed digital interface has been developed to accept real time digital pixel data from high resolution CCD cameras. The interface is currently in use with both a 640 X 486 12-bit digital infrared camera operating in non-interlaced mode at 30 frames per second, and a 756 X 484 8-bit digital visible camera operating in interlaced mode at 60 fields per second. Using programmable logic, the interface is reconfigurable to accept digital data from a variety of sensors at data rates of up to 18 megabytes per second. The buffered digital data is recorded on a hard disk array consisting of up to nine individual drives, with a present capacity exceeding 5.9 gigabytes. Continuous recording is achieved by implementing a loop function on the disk array.
