摘要： A laser projection system is provided comprising a laser source, projection optics, scanning optics, and a scanning controller. The laser source comprises at least two punctual sources P1, P2 configured to generate two optical beams. The scanning controller is configured to drive the scanning optics to define a fast scanning axis direction in which lines of an image are projected and a slow scanning axis direction in which the optical beams address successive lines of the projected image. The position of the respective punctual sources relative to each other and to an optical axis of the projection optics provides an angular misalignment of the first and second optical beams downstream of the projection optics. The respective punctual sources are positioned such that the first and second optical beams are misaligned in the slow scanning axis direction to a greater extent than in the fast scanning axis direction.
