Abstract
A sensor system includes a sensor, and an optical train adjustable to provide an optical beam to the sensor from a selected line of sight that may be varied. The optical train includes a wavefront error-introducing element in the optical train, which introduces a wavefront error that is a function of the selected line of sight. There is further a rigid-body wavefront error-correcting element in the optical train. The rigid-body wavefront error-correcting element has a spatially dependent correction structure with the nature of the correction being a function of the selected line of sight. The adjustment of the optical train to the selected line of sight moves the optical beam to the appropriate location of the rigid-body wavefront error-correcting element to correct for the corresponding introduced wavefront error of the wavefront error-introducing element at that selected line of sight.
