Three-dimension light field construction apparatus

摘要

A three-dimension light field construction apparatus is applied to constrict a light field on a viewing plane. The three-dimension light field construction includes a plurality of projectors and a rear-displaying unit. The projectors are arranged along a first axis, and each projector projects an imaging beam along a second axis perpendicular to the first axis. The rear-displaying unit comprises a linear Fresnel lens and a vertical diffuser, the linear Fresnel lens is close to the projectors. The rear-displaying unit makes each of the imaging beams converge on a virtual surface between the rear-displaying unit and the viewing plane for forming at least one intersection, so as to construct at least one light field on the viewing plane.
