    Abstract: An optical wireless power transfer system including a transmission module having a power light source configured to output power light; a communication light source configured to output communication light; a mirror disposed in a light path of the power light source and the communication light source and configured to pass the power light and reflect the communication light; and a transmitting processor configured to modulate the communication light to have a first modulation. The wireless power transfer system also includes a reception module having a photoelectric cell configured to receive the power light from the transmission module and generate power; a retro-reflector configured to retro-reflect the communication light back to the transmission module; and a receiving processor configured to control the retro-reflector to reflect the communication light to have a second modulation based on the power generated by the photoelectric cell.

    Abstract: An optical wireless power transfer system includes a transmission module, which includes a main light source configured to output a main light; a transmitting processor configured to modulate the main light to have a first modulation; a beam splitter configured to pass the main light as a power light; and a reception module. The reception module includes a retro-reflector configured to retro-reflect the main light back to the transmission module; and a receiving processor configured to control the retro-reflector to reflect the main light to have a second modulation based on a power generated by the main light. Further, the beam splitter is further configured to reflect the main light having the second modulation to a first photodiode included in the transmission module.
