Abstract

A Scan Head package including two 1D resonant electrostatic driven micro scanning mirrors with piezoresistive position detection was developed. The scanning frequency of the slow and the fast axis is 100Hz and 29,05kHz, allowing WVGA-resolution. Thereby the Scan Head design reduces vertical distortion strongly and can potentially be assembled automatically. In addition FPGA based video processing electronic was developed to improve the sorting of the picture information corresponding to the Lissajous figure with the objective of high picture contrast and a homogeneous brightness.
