OWPT (Optical Wireless Power Transmission) by image-guided laser-beam steering

Optical Wireless Power Transmission (OWPT) is one of the technologies of wireless energy transfer. OWPT uses optical light source as an energy emitter, and solar panel as an energy detector. With current trends of availability of large laser power source at lower prices and sophisticated image recognition technologies, OWPT increases its attention. In order to obtain high energy transfer efficiency in OWPT, precise control of laser illuminating position is required. We apply co-axially aligned optical system of imaging function and laser beam steering function to satisfy the requirement. At the presentation, we will introduce our approach of OWPT.
