Sports: 3-D TV’s Toughest Challenge

Here’s why live sports, the most popular 3-D shows, are the hardest to produce

Mirror, Mirror: In 3Ality Technica’s Beamsplitter rigs, a horizontally mounted camera looks through a mirror, and a vertically mounted camera sees the mirror’s reflection. This allows the cameras to be placed much closer together than in a more conventional setup and is useful for close-up shots.

If you’re one of the 24 million or so people around the world who purchased a 3-D television in 2011—or the 42 million doing so this year—you might know what it takes to watch 3-D on your home television: a pair of 3-D glasses. But you likely haven’t thought much about what it takes to produce the 3-D spectacle that comes to life in your living room. More cameras, or at least more lenses, you might think, and that’s probably about it.

Engineers Are Working on a Solar Microgrid to Outlast Lunar Nights

Future lunar bases will need power for mining and astronaut survival

The next time humans land on the moon, they intend to stay awhile. For the Artemis program, NASA and its collaborators want to build a sustained presence on the moon, which includes setting up a base where astronauts can live and work.

One of the crucial elements for a functioning lunar base is a power supply. Sandia National Laboratories, a research and development lab that specializes in building microgrids for military bases, is teaming up with NASA to design one that will work on the moon.

Trilobite-Inspired Camera Boasts Huge Depth of Field

New camera relies on “metalenses” that could be fabricated using a standard CMOS foundry

Inspired by the eyes of extinct trilobites, researchers have created a miniature camera with a record-setting depth of field—the distance over which a camera can produce sharp images in a single photo. Their new study reveals that with the aid of artificial intelligence, their device can simultaneously image objects as near as 3 centimeters and as far away as 1.7 kilometers.

Five hundred million years ago, the oceans teemed with horseshoe-crab-like trilobites. Among the most successful of all early animals, these armored invertebrates lived on Earth for roughly 270 million years before going extinct.

Reduce EMI and EMC Issues with Engineering Simulation Software

Electronic components and systems exist today in nearly all consumer and industrial products. A major design consideration in all electronics is electromagnetic interference (EMI) and compatibility (EMC). EMI and EMC issues are complex. They can be hard to detect and can be taxing to a design. With the use of engineering simulation software, design engineers can mitigate issues before entering the prototype testing phase. Avoiding the test-retest cycle with simulation can help save time and money all while delivering robust and reliable products.
