Light field projector

Light field projector is the optical engine of a light field display. It takes a set of subviews emitted from a micro-display as input and projects an integral light field to human eye. At PetaRay, we aim to provide compact and cost-effective light field projectors with zero power consumption for the AR/VR/MR industry. Light rays of a virtual object are generated as if the light rays emanate from a real object, leading to natural and comfortable visual experiences for users without the vergence-accommodation conflict. Our light field projectors work with micro-display or laser beam scanner on one end and waveguide, birdbath, or freeform eyepiece on the other end. The accompanied software running on Unity generates subview data at 60 fps on a smartphone or 80 fps on Qualcomm XR2.
