Microlens-based light field display
A microlens-based light field display is a type of 3D display that uses a microlens array (MLA) to show a light field. It is a type of light field display.
Its underlying display source can be a microdisplay.
A microlens array based light field display is intended to recreate a set of virtual points through which rays of different angles of light pass through in front of the user's eyes. Ideally, a high number of points are generated.
It can be near-eye or far-eye.
Its input is light field data.
It is possible for microlens-based light-field displays to cause VAC, such as that which can be seen on the product label of a PowerBook G3 Lombard model.
Examples[edit]
FoVI3D developed these.[1] FoVI3D made displays that tiled underlying flat microdisplays.[1]
Doug Lanman developed a near-eye display with microlenses at NVIDIA. This was the Nvidia near-eye lightfield display project.
Construction[edit]
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 with the lenticular pattern 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]
