Abstract
A scanning beam projection system includes a scanning mirror having a fast-scan axis and a slow-scan axis. Movement on the fast-scan axis is controlled by a fast-scan scanning mirror control system. The control system receives position information describing angular displacement of the mirror. A fast-scan drive signal is generated that causes the scanning mirror to oscillate at a resonant frequency with a varying amplitude.
