Abstract
The disclosure is directed to illumination-based charging of one or more portable devices. According to an embodiment of the disclosure, an illumination-based charging pad includes a platform, a plurality of illumination sources, a plurality of photosensitive detectors, and a controller. The controller performs a scan by activating the illumination sources and detecting reflected illumination from an illuminated surface of at least one portable device disposed upon the platform. The controller determines a set of one or more illumination sources that are at least partially overlaid by the portable device based upon the detected illumination. The controller selects one or more illumination sources for charging the portable device at least partially based upon the set of one or more illumination sources determined to be overlaid by the portable device.
