Abstract
This paper presents a metasurface-enhanced Shack-Hartmann wavefront sensor (meta SHWFS) that achieves significantly higher sampling density and a larger angular field of view compared to traditional Shack-Hartmann wavefront sensors. The meta SHWFS, with a sampling density of 5963 per mm² and a maximum acceptance angle of 8°, is experimentally validated and demonstrates single-shot phase imaging of complex objects, including biological tissue patterns. This advancement opens new possibilities for wavefront characterization using metasurface technology.
