摘要
A laser scanner with a 2D resonant electrostatic micro-mirror has improved aiming visibility, reduced tilt dependence and improved read range. The laser scanner has a field of view that defines a 3D volume and utilizes a laser beam in a light path that is thin relative to the 3D volume. Physical pixel height is enlarged to aid optical imaging plane alignment. A selective filter centered on the lighting wavelength is placed in the image path. The height of the pixel may be artificially induced to be m*w, where m is the lens magnification and w is the light thickness. Diagonal progressive scanning is used to maximize the frequency values so shock resistance of the mirror is increased.
