Researchers have developed the first megapixel photon-counting camera based on new-generation image sensor technology that uses single-photon avalanche diodes (SPADs). The new camera can detect single photons of light at unprecedented speeds, a capability that could advance applications that require fast acquisition of 3D images such as augmented reality and LiDAR systems for autonomous vehicles.

“Thanks to its high resolution and ability to measure depth, this new camera could make virtual reality more realistic and let...

New technology creates color 3D images that don’t require special viewing devices. A new type of display creates 3D images by using a laser to form tiny bubbles inside a liquid “screen.” Instead of rendering a 3D scene on a flat surface, the display itself is three-dimensional, a property known as volumetric. This allows viewers to see a 3D image in the columnar display from all angles without any 3D glasses or headsets. The volumetric bubble display to create changeable color graphics.

“Creating a full-color updatable volumetric display is challenging because many three-dimensional pixels, or voxels, with different col...
