Abstract

Herein, a lucid meta-holographic approach leveraging geometric phase metasurfaces and photonic crystal surface-emitting lasers is presented. Such a straightforward technique inherently enables polarized structured light projection with opposite circular polarization states, effectively doubling the field of view for depth sensing applications. Furthermore, the innate polarization state of projected light provides enhanced resistance to environmental interference. To demonstrate the practical utility of this method, an integrated depth sensing system based on the geometric phase meta-hologram has been developed and successfully detects targets at an operating distance of 75 cm, paving the way for advanced 3D sensing applications in various fields.
