A method for simultaneously generating two or more substantially one-dimensional scan line image portions (SL1, SL2) 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 (SL1, SL2) of said two-dimensional image: during a first time period, 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 (G1, G2) of said plurality of scan line image data groups, wherein said configuring includes: adjusting a first modulating element group of said plurality of modulating elements that is disposed in a first plurality of said rows in accordance with a first scan line image data group of said plurality of scan line image data groups such that two or more modulating elements disposed in each column of said first modulating element group are adjusted in accordance with an associated image pixel data portion of said first scan line image data group, and adjusting a second modulating element group including modulating elements disposed in a second plurality of said rows in accordance with a second scan line image data group of said plurality of scan line image data groups such that two or more modulating elements disposed in each column of said second modulating element group are adjusted in accordance with an associated image pixel data portion of said second scan line image data group; and during a second time period, 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 such that said modulated light field is anamorphically imaged and concentrated to form first and second substantially one-dimensional scan line images on said imaging surface. during a first time period, 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 (G1, G2) of said plurality of scan line image data groups, wherein said configuring includes: adjusting a first modulating element group of said plurality of modulating elements that is disposed in a first plurality of said rows in accordance with a first scan line image data group of said plurality of scan line image data groups such that two or more modulating elements disposed in each column of said first modulating element group are adjusted in accordance with an associated image pixel data portion of said first scan line image data group, and adjusting a second modulating element group including modulating elements disposed in a second plurality of said rows in accordance with a second scan line image data group of said plurality of scan line image data groups such that two or more modulating elements disposed in each column of said second modulating element group are adjusted in accordance with an associated image pixel data portion of said second scan line image data group; and during a second time period, 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 such that said modulated light field is anamorphically imaged and concentrated to form first and second substantially one-dimensional scan line images on said imaging surface. adjusting a first modulating element group of said plurality of modulating elements that is disposed in a first plurality of said rows in accordance with a first scan line image data group of said plurality of scan line image data groups such that two or more modulating elements disposed in each column of said first modulating element group are adjusted in accordance with an associated image pixel data portion of said first scan line image data group, and adjusting a second modulating element group including modulating elements disposed in a second plurality of said rows in accordance with a second scan line image data group of said plurality of scan line image data groups such that two or more modulating elements disposed in each column of said second modulating element group are adjusted in accordance with an associated image pixel data portion of said second scan line image data group; and during a second time period, 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 such that said modulated light field is anamorphically imaged and concentrated to form first and second substantially one-dimensional scan line images on said imaging surface.
