Camera inspired by insect eyes can see 180 degrees, has almost infinite depth of field
Technologists have been drawing inspiration from the insect world for a long time. And folks working on robotics really seem to love their creepy-crawlies and buzzing arthropods. Researchers at the University of Illinois are looking to our eight-legged planet mates, not for mobility lessons, but as a reference for a new camera design. The system mimics the vision of bees and mantises by combining multiple lenses on a half hemisphere to provide a 180-degree view with a nearly infinite depth of field. The optics themselves are described as "soft, rubbery" and each individual microlens is paired with its own photodiode. The work gets us a heck of a lot closer to the dream of a digital fly eye than previous efforts, though we're likely still quite a while from seeing applications outside of the lab. DARPA funding suggests the artificial compound eyes may have a future in surveillance, though the researchers also see uses for it in medicine.
'Trilobite' compound eye puts a Paleozoic spin on mobile camera design
Extinct marine arthropods make for great design references -- just ask Andreas Brückner. The Fraunhofer Institute of Applied Optics and Precision Engineering researcher has taken a cue from the trilobite in creating a 1.4mm thin "cluster eye" camera to take 221 images at 39 pixels per side to form a 700 x 550 (0.38 megapixel) composite. At this point, it's also capable of recording 13 frames per second for video, and with a size like that, if they can bump up the specs it could pave way for smaller camera components in mobile phones. Not anytime soon, of course, as it's still in the research state (and it's just one of many camera research projects out there). The next step for Brückner and company is shrinking the aforementioned design to 1mm thin (and up the video to 30fps), as well as 1.5mm variant with one megapixel resolution.
