Abstract:
1. A method for simultaneously generating two or more substantially one-dimensional scan line image portions of a two-dimensional image on an imaging surface, said two-dimensional image being stored in an image data file including a plurality of scan line image data groups, each scan line image data group including a plurality of image pixel data portions representing an associated one-dimensional scan line image portion of said two-dimensional image, the method comprising: configuring a spatial light modulator including a plurality of light modulating elements arranged in a plurality of rows and a plurality of columns in accordance with at least two scan line image data groups of said plurality of scan line image data groups, wherein said configuring includes: utilizing the configured spatial light modulator to generate first and second substantially one-dimensional scan line images on said imaging surface by directing homogenous light onto the plurality of light modulating elements such that the configured first and second modulating element groups generate a modulated light field that is transmitted through an anamorphic optical system onto said imaging surface, wherein the anamorphic optical system is formed and positioned such that said modulated light field is anamorphically imaged and concentrated to form said first and second substantially one-dimensional scan line images on an elongated imaging region of said imaging surface.
