摘要： In one embodiment, described herein is an apparatus for projecting linear illumination fanned out along the slow axis of a laser source array. In addition to the laser source array, the apparatus can include a number of fast axis collimators (FACs) to collimate the laser beams from the laser source array along the fast axis, a cylinder lens array for converting the collimated laser beams to parallel laser beams, and a prism array pair for reducing the pitch of the parallel laser beams. The system further includes a first cylinder lens for focusing the laser beams from the prism array pair onto a MEMS mirror, which redirects the laser beams as a linear laser beam towards a predetermined direction.
