Abstract: An arrangement for determining light beam position in an electro-optical reader, image projector and like devices includes a drive for moving a scanning light beam at a scan frequency across a target as a scan line, and an electro-optical feedback assembly operatively connected to the drive, for optically detecting scan line position during beam movement, and for generating a feedback signal at the scan frequency, the feedback signal being indicative of the scan line position. A feedback coil in the drive is eliminated to avoid electromagnetic coupling between multiple coils in the drive.

Abstract: A laser projection device (LPD) suitable for displaying color images is disclosed. The LPD is used to excite various photoluminescent materials located on a display screen so as to produce multi-color displays. Additionally, the screen may be movably mounted so as to reduce laser speckling.
