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.
其他摘要	一种成像装置，包括激光二极管的线性阵列，其适于提供包括多个间隔开的光束的光输出。聚焦光学器件被配置为从所述间隔开的光束形成多个图像点，图像点沿第一轴间隔开。图像点沿第一轴具有不均匀的间隔。通过沿光敏板扫描线性阵列，并相应地定时激光器的发射，光敏板上的每个像素点可以由来自激光器阵列的一个图像点成像。图像点的不均匀间隔可以提供从激光元件散热的优点，并减少光敏板上的一些印刷伪影。
