摘要:
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.
