Advanced Display Holography

Electronic display system for computational holography

We present an electro-optical apparatus capable of displaying a computer generated hologram (CGH) in real time. The CGH is calculated by a supercomputer, read from a fast frame buffer, and transmitted to a high-bandwidth acousto-optic modulator (AOM). Coherent light is modulated by the AOM and optically processed to produce a three-dimensional image with horizontal parallax.

Light-in-flight digital holography display.

We present a digital speckle-pattern interferometric setup that can be operated at TV frame rates (30 ms) to display the locus of the points at which the optical-path difference between the reference and object beams is within the coherence length. Experimental results are shown.

Augmenting digital jewelry with advanced display capacities

In this paper, we present ways to enhance digital jewelry with new generation displays. We first present ways to improve display capabilities on existing pieces of jewelry by using curved deformable displays and projectors. In a second part, we focus on the particular case of wristwatches, presenting new results about interaction on wristband and propose new usages unlocked by the use of such d...

Blink: Advanced Display Multiplexing for Virtualized Applications

Providing untrusted applications with shared and dependable access to modern display hardware is of increasing importance. Our new display system, called Blink, safely multiplexes complex graphical content from multiple untrusted virtual machines onto a single Graphics Processing Unit (GPU). Blink does not allow clients to program the GPU directly, but instead provides a virtual processor abstr...
