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.
