Abstract
An imaging device is disclosed for projecting individually controllable laser beams onto an imaging surface that is movable relative thereto in X-direction. The device includes a plurality of semiconductor chips comprising a plurality of individually controllable laser emitting elements arranged in a two dimensional array of M rows and N columns. The chips are mounted on a support in at least one pair of rows, such that each pair of adjacent chips in Y-direction are offset from one another in the X-direction, and the laser beams are substantially uniformly spaced in the Y-direction. The chips are arranged such that corresponding elements in any group of three adjacent chips in the X and Y-directions lie at the apices of congruent equilateral triangles. A plurality of GRIN rod based lens systems focuses the beams for each of the chips onto the imaging surface.
