Paper Abstract
We present the use of a micromirror to dynamically improve an optical wireless communications link. The
signal-to-noise ratio (SNR) is improved by directing the output of a 675 nm laser diode modulated at 10
MHz toward a receiver and by varying the divergence of the output beam using a varifocal, tip-tilt-piston
micromirror. The SNR has a dynamic range of 30 dB for a diffuse source, all by optimizing the overall shape
and direction of the mirror.
