Abstract

A light scanner includes a beam deflector supported for rotary motion to deflect an incoming light beam into an image field in response to being rotationally aligned. A motor mechanically couples to rotate the deflector in and out of the rotational alignment. The beam deflector scans the image field with the deflected incoming light in response to being rotated. A gas permeable screen structure partially encloses a region adjacent the rotating beam deflector and reduces gas turbulence in the region of the deflector.
