Light-field pixel for detecting a wavefront based on a first intensity normalized by a second intensity

摘要

A light-field pixel for detecting a wavefront, the light-field pixel comprises an aperture layer, a light detector layer, and a processor. The aperture layer has a non-conventional aperture and a non-conventional aperture. The non-conventional aperture has a higher gradient of transmission at normal incidence than the conventional aperture. The light detector is configured to measure a first intensity of light through the non-conventional aperture and a second intensity of light through the conventional aperture. The processor is configured to detect the wavefront based on the first intensity normalized by the second intensity.
