英文摘要	An imaging device comprising a linear array of laser diodes that are adapted to provide an optical output comprising a plurality of spaced-apart optical beams. Focusing optics are configured to form a plurality of image points from said spaced-apart optical beams, the image points being spaced apart along a first axis. The image points have a non-uniform spacing along the first axis. By scanning the linear array along a photosensitive plate, and timing the firing of lasers accordingly, every pixel point on the photosensitive plate can be imaged by one of the image points from the laser array. Non-uniform spacing of the image points can provide advantages in heat dissipation from the laser elements, and reduction of some printing artifacts on the photosensitive plate.
