Apparatus and method for projecting an image to be viewed over the viewing distance of the extended

摘要

The laser beam is swept as a pattern of scan lines on the projection plane by the scanning mirror. Image is generated the selected pixels arranged along each scan line is illuminated. In the focal position that is located between the projection plane and the scanning mirror, the laser beam is shaped optically by focusing the laser beam to form a beam waist with a scan size that is proportional to the resolution and expanded over to the viewing distance, each scan line with a high resolution of desired with a large number of pixels to form the desired.
