Reflective pupil relay optics for mems scanning system

An optical module, comprising:

• a fast axis mirror arranged along a first path to receive a combined RGB laser beam, the fast axis mirror being drivable to scan the combined RGB laser beam along a fast axis;
• three optical surface magnification mirrors receiving the combined RGB laser beam as it is scanned along the fast axis, wherein the three optical surface magnification mirrors comprise:
• a first concave mirror receiving the combined RGB laser beam as it is scanned along the fast axis and reflecting the combined RGB laser beam along a first internal path;
• a first convex mirror arranged along the first internal path to receive the combined RGB laser beam, the first convex mirror reflecting the combined RGB laser beam along a second internal path;
• and
• a second concave mirror arranged along the second internal path to receive the combined RGB laser beam, the second concave mirror reflecting the combined RGB laser beam toward a slow axis mirror;
• wherein the first concave mirror, the first convex mirror, and the second concave mirror cooperate to magnify a diameter of the combined RGB laser beam;
• the slow axis mirror receiving the combined RGB laser beam after magnification, the slow axis mirror being drivable to scan the combined RGB laser beam along the slow axis;
• and
• an Offner mirror relay receiving the combined RGB laser beam as it is scanned along the slow axis and reflecting the combined RGB laser beam along a second path toward an exit aperture of the optical module.
