Laser graphic video display using silicon scanning mirrors with vertical comb fingers

Abstract

We acquired a two-dimensional (2D) laser-vector graphic video image using 1500 mum x 1200 mum silicon scanning, mirrors, with vertical comb fingers. Vector image signals from the graphic board were applied to two scanning mirrors, and a SHG green laser was directly modulated to shape independent graphic images. These scanning mirrors were originally designed for laser raster video display as a galvanometric vertical scanner, and are controlled perfectly h the ramp waveform of 60 Hz with the duty cycle of 90%.
