Abstract

In various embodiments of the present invention data is transmitted in light emitted by a light source by generating a continuous-time data signal and generating, based thereon, a drive signal that provides power to the light source, thereby causing the light source to emit light; variations in the amplitude of the drive signal represent information in the continuous-time data signal. A change in average power delivered to the light source as a result of the variations in the amplitude of the drive signal is detected and power to the light source is adjusted to compensate.
