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.
