Abstract
A method for displaying or capturing an image comprises directing an illumination beam onto a mirror of a highly resonant, mirror-mount system and applying a drive signal to a transducer to deflect the mirror. In this method, the drive signal has a pulse frequency approaching a resonance frequency of the mirror-mount system. The method further comprises reflecting the illumination beam off the mirror so that the illumination beam scans through an area where the image is to be displayed or captured, and, addressing each pixel of the image in synchronicity with the drive signal to display or capture the image.
