Claim One:
1. An electronic image printer of the type adapted to expose a photosensitive material with light derived from a source of incoherent light to print an image on the photosensitive material of a selected subject comprising: laser means for providing a beam of coherent light; means for modulating said coherent light beam in response to an electronic signal corresponding to the image of the subject selected for printing; a laser addressed liquid crystal light valve; light scanning means including at least one light reflective scanning surface for sweeping said modulated coherent light beam over the area of said liquid crystal light valve so as to address said liquid crystal light valve; first optical means for focusing the light emanating from the source of incoherent light onto said light reflective scanning surface for projection by said light scanning means to uniformly illuminate the entire area of said liquid crystal light valve previously addressed by said beam of coherent light; and second optical means for directing the incoherent light transmitted through said liquid crystal light valve to expose the photosensitive material to the image of the subject selected for printing.
