Abstract
The embodiments described herein provide scanning laser devices that include a relay optic between scanning surfaces. In general, the relay optic is configured to reimage the laser beam reflecting from a first scanner onto the second scanner. Specifically, the relay optic is configured to reimage a laser beam reflected from over an angular range from a first scanning surface of a first scanner onto the scanning surface of the second scanner. This can effectively make the exit pupil of the scanners substantially coincident, and thus can reduce the exit pupil disparity between the scanners that would otherwise exist.
