Abstract:
1. A method for generating a substantially one-dimensional scan line image on an imaging surface of a scan structure, the method comprising: generating homogenous light such that the homogenous light forms a substantially uniform two-dimensional homogenous light field; modulating the homogenous light in accordance with the predetermined scan line image data such that the modulated light forms a two-dimensional modulated light field including one or more image features; anamorphically imaging and concentrating the modulated light such that the imaged and concentrated modulated light forms the substantially one-dimensional scan line image on an elongated imaging region of the imaging surface; and synchronizing a cross-scan movement of the imaging surface with said modulating the homogenous light such that an image feature of said scan line image scrolls in the cross-scan direction at the same rate as said cross-scan movement of the imaging surface, wherein anamorphically imaging and concentrating the modulated light comprises: imaging, projecting, and magnifying said modulated light in a cross-process direction using first and second cylindrical or acylindrical focusing lens, and imaging and concentrating said modulated light in a direction parallel to a process direction using a third cylindrical or acylindrical focusing lens.
