Directional visible light communication signal enhancement using a varifocal micromirror with four degrees of freedom
2016
Fifteenth International Conference On Solid State Lighting And Led-Based Illumination Systems
We present the use of a micromirror to dynamically improve an optical wireless communiciations 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.
