1. A waveguide-based light field camera system for sensing the magnitude and direction of the individual light fields, the system comprising:
an optical waveguiding structure containing in-coupling and out-coupling regions;
a lens structure positioned to capture out-coupled light field radiation from the out-coupling regions of the optical waveguiding structure;
a photosensitive pixelated array located after said lens structure for collecting the out-coupled light field radiation and converting the out-coupled light field radiation into electrical signals,
wherein the in-coupling region of the said waveguiding structure is composed of multiple in-coupling sub-regions, and
wherein the in-coupling sub-regions include diffractive structures with different diffractive properties.
