Abstract
An imaging system includes a body, a stage coupled to the body, and an actuator coupled to the body and the stage. The actuator is configured to move the stage in one or more directions relative to the body. The imaging system also includes a focal plane array including one or more detectors and coupled to the stage and a controller coupled to the actuator. The controller is configured to determine a velocity of the body and to cause the actuator to backscan the stage in the one or more directions at a drive velocity corresponding to the velocity of the body. Moreover, the controller is communicatively coupled to the one or more detectors and causes the one or more detectors to capture image data during the backscan.
