Steerable diverging angular dispersion beam for wireless optical power transfer

A significant challenge faced by Wireless Optical Power Transfer (WOPT) using the Resonant Beam Charging (RBC) method is the restrictive alignment requirement. In this study, we examine the utilization of a diverging angular dispersion beam and active beam steering to enhance the likelihood of identifying and maintaining a resonant link. The system exhibits significant improvements compared to conventional systems that utilize pencil beams. This enhancement is observed during the initial search for the receiver position, and it contributes to maintaining resonance cavity between the two beam types. These findings highlight the potential of utilizing diverging angular dispersion beams for real-time charging applications in future research.
