Title:
- A Volumetric Display Based on a Rim-Driven Varifocal Beamsplitter and LED Backlit LCD
Presenter(s):
Description:
We demonstrate a volumetric display providing high resolution, full color, real images with 10 addressable depth planes and correct focus and vergence cues for the viewer. The display is centered around a novel optical element; a large-aperture, rim-driven, adjustableresonance, varifocal beamsplitter.
A full color Liquid Crystal Display (LCD), backlit by an actively addressed LED array, is the primary image source. The backlight is synchronized to the vibrating beam-splitter and strobed to fix the position of image planes in a volume. A fixed concave mirror in the optical path makes the images real, and places them out in front of the apparatus. Depths exceeding 30 cm are achieved with a 30 cm diagonal displayed image.
