Patent ID: 8472104

Claim:
A single-pass imaging system comprising: a homogenous light generator for generating homogenous light such that the homogenous light forms a substantially uniform homogenous light field; a spatial light modulator including: a plurality of light modulating elements arranged in a two-dimensional array and disposed in the homogenous light field such that each said modulating element receives an associated homogenous light portion of the homogenous light, and a controller for individually controlling the plurality of modulating elements such that each modulating element is adjustable, in response to an associated control signal generated by the controller, between a first modulated state and a second modulated state, whereby when said each modulating element is in said first modulated state, said each modulating element modulates an associated received homogenous light portion such that an associated modulated light portion is directed in a corresponding predetermined direction, and when said each modulating element is in said second modulated state, said each modulating element modulates the associated received homogenous light portion such that the associated modulated light portion is prevented from passing along said corresponding predetermined direction; and an anamorphic optical system positioned to receive said modulated light portions from said each modulating element disposed in said first modulated state, and arranged to concentrate said modulated light portions such that the concentrated modulated light portions produce an elongated scan line image, wherein the plurality of light modulating elements are arranged in a plurality of rows and a plurality of columns, wherein each said column includes an associated group of said plurality of light modulating elements, and wherein the anamorphic optical system is arranged to concentrate modulated light portions received from each associated group of said plurality of light modulating elements of each said column onto an associated scan line portion of said elongated scan line image.
