A light light modulators (SLMs) to modulate a uni-form backlight and render apparently direc-tional light rays. The light field display part only occupies 20-30° FOV, and the rest is filled by non-light field images, which means that the periphery of the central vision does not have the advantages of zooming of light field display; SIGGRAPH 2013 Emerging Technologieshttps://research. (L: distance from main lens to microlens array, b: distance from microlens array to image sensor, dr: radial distortion , dt: tangential Distortion. profiling photometer, predeter mined sampling proto- Unlike conventional displays, the light field display can create natural 3D images as it demonstrates the depth and sides of the projected object depending on a viewer’s perspective. A light field capture system samples these rays of light to record a four dimensional representation of a given environment. As a wearable device, a near-eye display should have a compact form factor and be lightweight.
