LASER PROJECTOR AND IMAGE PROJECTION METHOD |
摘要 |
A laser projector comprises an oscillation device for displacing at least one of a plurality of optical elements, which constitute the projection optical system of the laser projector, periodically along the direction of the optical axis of laser light. The laser projector reduces the speckle of a projection image on an arbitrary screen to such an extent as it cannot be recognized with human eyes, without having a significant effect on the image resolution, by periodically displacing the position of the smallest spot of laser light projected from the projection optical system. An image projection method is also provided. |
