56.6L: Late‐News Paper: Modular Multi‐Projection Multi‐View Autostereoscopic Display using MEMS Laser Projectors

Abstract

A new modular multi‐projection multi‐user multiview autostereoscopic display structure based on microelectromechanical systems (MEMS) laser projectors is presented. The system contains an array of MEMS laser projectors, a vertical diffuser, and the driving electronics. Each projector provides a slit of the whole image observed through the vertical diffuser. The structure does not require super position of the content among the projectors. Unlike similar type of displays, the size of the projection display hardware decreased dramatically. The structure has the capability to provide horizontal expansion in the screen size, and in number of different perspectives shown. Mentioned capabilities can be enhanced by using more projectors, by increasing the distance between projectors and the screen, and by changing the diffusion angle of the vertical diffuser in the minor axis. The inhouse built prototype with 18 projectors displays an image with a resolution of 234times848, and 36 different perspectives. The size of the image at the screen is 16 cm x 72 cm

Wearable and augmented reality displays using MEMS and SLMs

“…When multiple pinholes are used per eye, a sense of blurring can also be provided for out of sight objects, hence a more natural 3D experience is delivered, though at the cost of worsened light efficiency. In another work, we implemented a multiview 3D system using an array of pico-projectors that can serve multiple glasses-free users simultaneously [8]. Eyewear displays 1111411 placed side by side, and a vertical diffuser is used to spread the light in vertical direction.…”
