Disclosed are a metasurface-based structured light 3D imaging system and method, which use a metasurface-based control device to realize high-quality control of a laser beam, use a MEMS micromirror to scan and project the laser beam, and realize high-precision reconstruction of 3D information of the surface of an object together with related structured light design and demodulation methods. The invention realizes fine control of a structured light, improves the quality of a structured light field, reduces laser speckles and improves power, thus improving 3D imaging precision and robustness.

Metasurface-based structured light 3D imaging system and method

A capacitive power transfer system can include a power transmitter having one or more primary side filter components, a communications modulator, and transmitter capacitive couplers; and a power receiver having receiver capacitive couplers capacitively coupled to the transmitter capacitive couplers, one or more secondary side filter components, and a communication demodulator. The one or more primary side filter components and the one or more secondary side filter components can be selected to provide power amplifier operation at a power delivery frequency and act as a stable gain high pass filter above a communications cutoff frequency that is higher than the power delivery frequency.
