Abstract: 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.

Abstract: A laser beam is swept by a scan mirror as a pattern of scan lines on a projection surface. The scan mirror moves at a variable speed along each scan line. Each scan line has a number of pixels. The pixels have time durations proportional to the variable speed of the scan mirror. A profile memory stores the time durations of the pixels. A controller causes selected pixels arranged along each scan line to be illuminated for the time durations stored by the profile memory to produce an image of uniform brightness and of uniformly sized pixels and in color.

Abstract: Electrical interference between resonant, drive and line frequencies in a drive is reduced by selecting the resonant frequency to be non-harmonically related to the drive and line frequencies. The drive is of beneficial use in a lightweight, compact image projection module operative for causing selected pixels in a raster pattern to be illuminated to produce a non-distorted image of high resolution of VGA quality in color.

Abstract translation: 通过选择与驱动和线路频率非谐波相关的谐振频率来减小驱动器中谐振，驱动和线路频率之间的电气干扰。 该驱动器在轻量级紧凑的图像投影模块中是有益的，该模块可操作用于使得光栅图案中的所选像素被照亮以产生VGA质量的高分辨率的非失真图像。
