ABSTRACT:
An optical system focuses a portion of electromagnetic energy into a spot on a focal plane and rotates the focused spot about an optic axis. A plurality of detectors is disposed in a detector plane. The array of detectors is arranged in a plurality of sets of such detectors. Each one of such sets of detectors is disposed along a different region extending radially from a central region of the array. When the detector and focal planes are skewed, a processor processes signals produced by a selected one of the plurality of sets of detectors. The selected one of the sets is the set disposed in one of the radially extending regions disposed along, or adjacent to, a line formed by the intersection of the skewed detector and focal planes.
