Abstract

We discuss magnetic actuation for Microvision’s bi-axial scanners for retinal scanning displays. Compared to the common side-magnet and moving-coil approach, we have designed, assembled and tested a novel magnet configuration, with magnets above and below the moving coil. This design reduces the magnet sizes significantly without sacrificing performance, and opens further improvement paths as well.
