ABSTRACT:
A step stare scanning device includes a mirror with a plurality of facets mounted to a mechanism which substantially simultaneously rotates the mirror about a first axis while orbiting the mirror about a second axis. The rotating and orbiting motion creates a step stare scanning pattern from a constant rotary input. The field of view of an associated detector array is increased while minimizing detrimental effects of known stop-start mechanisms.
