ABSTRACT:
A method and apparatus for holding a line of sight in a scanning imaging system wherein there is continuous relative movement between the field of view of the system and an image plane. A descan mechanism temporarily holds a line of sight within a field of regard as a scanning mechanism such as a gimbal continuously moves imaging optics relative to the object space. The descan mechanism descans the image, the descan mechanism's relative movement being opposite to the direction of movement of the gimbal, so as to hold a line of sight for a time period and thereafter snap to a new field of view to thereafter descan the new line of sight for another time period. With the present invention a scanning system can be used with an imaging device requiring time integration for greater sensitivity, such as a staring electronic detector array or photographic film, without necessitating the physical scanning motion to be cyclically stopped and restarted.
