Blazed diffraction scanner |
摘要 |
A scanner includes a laser for projecting a laser beam at a facet having a blazed diffractive grating thereon. The facet is rotated relative to the laser to traverse the laser beam across the grating to diffract the laser beam into a scan line. The blazed diffractive grating may be readily manufactured using injection molding or photolithograhic manufacturing techniques.
