摘要:
A speckle contrast reducing method for a laser scanning projection system includes the following steps. Firstly, a laser beam is provided. The laser beam is projected on a projection surface according to a first scanning trajectory, thereby generating a first image frame. Sequentially, the laser beam is projected on the projection surface according to a second scanning trajectory, thereby generating a second image frame at an image refresh rate. Moreover, the second scanning trajectory of the second image frame is shifted by a displacement from the first scanning trajectory of the first image frame along a slow-axis direction.
