Paper Abstract

Magnetically-actuated micromachined scanning mirrors have been developed for pico-projectors using laser beam scanning (LBS). The human vision system readily detects imperfections in a LBS display, which become objectionable when scanned beam trajectory errors have amplitudes on the order of only parts per thousand, depending on the human vision system's sensitivity to the type of error and whether it is static or dynamic. The paper describes the overcoming of such challenges to achieve a high quality LBS projection.
