A microlens-based light field display is a type of 3D display that uses microlenses to show a light field. It is a type of light field display.
It can be near-eye or far-eye.
Its input is light field data.
The primary function of a microlens-based light field display is the depth capability. The secondary function is the range of viewpoints.
Examples
FoVI3D developed these.[1]
Doug Lanman developed a near-eye display with microlenses at NVIDIA in the year +2012.
FoVI3D made displays that tiled underlying flat microdisplays.[1]
Construction
A microlens-based light field display is based on an underlying 2D flat panel display. There is a grid of microlenses on top of the display.
Each microlens has multiple pixels underneath it. Each pixel generates a ray that has a unique origin and angle when it comes out of a microlens.[1]
Two lenticular sheets perpendicular to each other can be used to emulate a microlens array.[2]
The spatial resolution of a simultaneous light field display is proportional to the ratio of the microlens focal length to the distance of the display from the eye.[3]
An optical element to block the cross talk from one microlens to the next is called a baffle.[1]
Douglas Lanman's Nvidia near eye display
Douglas Lanman's NVIDIA research publication's display used two Sony ECX332A OLED microdisplays as the light sources.[3]
It used microlenses from a Fresnel Technologies #630 rectangular plano-convex microlens sheet.[3] The microlenses had a focal length of 3.3 millimeters and lens width of 1.0 millimeters. The microlenses were oriented with the planar surface facing the viewer.[3]
It was demonstrated at SIGGRAPH 2013.[4]
A copy of the project was made in about the year +2015 by Richard Assar, who used the same components as the original project.[5]
