Abstract
A system comprises a transmitter including a laser configured to generate a laser beam directed at a spot on a surface, and a laser driver connected to the laser and configured to modulate input data onto the laser beam. The system may further comprise a receiver including an optical detector configured to decode received light into raw data, a signal processor configured to decode the raw data into the original input data, and telescope optics configured to receive light reflected from the spot on the surface, collimate the light and converge the light onto the optical detector.
