A microfabricated light collimating screen is provided. A microfabricated
screen, in one form, is made from a photopolymer such as SU-8 material.
It is able to collimate light in two dimensions and for improved degrees
of collimation. It may also be directly patterned onto image sensors or
light sources in order to achieve direct collimation. The fabrication
method is large-area compatible and inexpensive. The proposed screens may
be useful for position detection of objects, such as in the paper mover,
in printers and copy machines.
