ARRANGEMENT FOR AND METHOD OF PROJECTING AN IMAGE TO BE VIEWED OVER EXTENDED VIEWING RANGE |
摘要 |
A laser beam is swept by a scan mirror as a pattern of scan lines on a projection surface. Selected pixels arranged along each scan line are illuminated to produce an image. The laser beam is optically modified to form each scan line with a desired high resolution having no less than a desired large number of the pixels over an extended viewing range, by focusing the laser beam to form a beam waist having a scan dimension proportional to the resolution at a focal location positioned between the scan mirror and the projection surface.
