1. A scanned beam imager, comprising; a beam director for scanning a beam of light across a field-of-view, a light detector for detecting light from the beam scattered by the field-of-view, and a controller that modifies the phase of pixels captured by said light detector responsive to the motion of objects in the field-of-view; and further comprising a motion detector coupled to said controller for measuring the motion of objects in the field-of-view, wherein said motion detector includes software for analyzing the apparent motion in captured images, and wherein said software for analyzing the apparent motion in captured images includes software for examining the skew of a machine readable symbol and for adjusting the skew if needed.
