Paper Abstract

The concept of an afocal IR scanner is presented, showing how two distinct fields of view are obtained simultaneously, using only a single detector and sharing the same scan mechanism. The resulting system may view two separate directions at the same time, or may examine the same scene with different magnifications, but is more compact than two individual scanners performing the same task. The commonality of scanning and imaging components in both optical paths, and the requirement for efficient optical switching, place unique demands on the design of the imaging optics within the scanner.
