Patent ID: 8405913

Claim:
An anamorphic optical projection system for anamorphically imaging and concentrating a two-dimensional light field to generate a substantially one-dimensional line image that extends in a cross-process direction on an imaging surface, the optical projection system comprising: a cross-process optical subsystem including at least one cross-process cylindrical/acylindrical optical element arranged to image said two-dimensional light field in a cross-process direction on the imaging surface, the cross-process direction being perpendicular to the process direction; and a process-direction optical subsystem including at least one process-direction cylindrical/acylindrical optical element arranged to focus said two-dimensional light field in the process direction on the imaging surface, wherein the two-dimensional light field has a first width in the cross-process direction and a first height in the process direction, and wherein the process-direction optical subsystem comprises at least one cylindrical/acylindrical lens that is shaped and positioned to concentrate the two-dimensional light field in the process direction onto the imaging surface in the process direction such that said substantially one-dimensional line image has a second height in the process direction that is at least three times smaller than the first height of the two-dimensional light field.
