Optical microphone developed by CMU researchers sees sound like never before – BIOENGINEER.ORG

A camera system developed by Carnegie Mellon University researchers can see sound vibrations with such precision and detail that it can reconstruct the music of a single instrument in a band or orchestra. A camera system developed by Carnegie Mellon University researchers can see sound vibrations with such precision and detail that it can reconstruct … Read more

Pigment or optical illusion? What makes this berry blue | CU Boulder Today

Banner image: Detail shot of Lantana strigocamara in the Ramaley Greenhouse. (Credit: Patrick Campbell / CU Boulder) On a beautiful fall day in 2019, Miranda Sinnott-Armstrong was walking down Pearl Street in Boulder, Colorado when something caught her eye: a small, particularly shiny blue fruit, on a shrub known as Lantana strigocamara. While its tiny … Read more

Researchers take optical coherence tomography to the next level – BIOENGINEER.ORG

WASHINGTON – Researchers have developed an enhanced version of optical coherence tomography (OCT) that can image biomedical samples at higher contrast and resolution over a wider 3D field of view than was previously possible. The new 3D microscope could be useful for biomedical research and eventually enable more accurate medical diagnostic imaging. WASHINGTON – Researchers … Read more

Creepy Optical Illusion Makes It Look Like a Black Hole Is Coming to Get You

A new optical illusion can trick most of us into perceiving an expanding black hole, new research reports. The image is completely static, but researchers say it gives people “a growing sense of darkness, as if entering a space voided of light”. The illusory forward motion is probably our mind’s way of preparing us for … Read more

This New Optical Illusion Is Strong Enough To Trick Our Reflexes

The ‘expanding hole’ is an illusion new to science, strong enough to prompt the human eye pupils to dilate in anticipation of entering a dark space. Credit: Laeng, Nabil, and Kitaoka “Expanding hole” illusion deceives our pupils to expand in anticipation of expected decrease in light. An optical illusion, that is new to science, appears … Read more

A New Quantum Technique Could Change How We Study The Universe

There’s a revolution underway in astronomy. In fact, you might say there are several. In the past ten years, exoplanet studies have advanced considerably, gravitational wave astronomy has emerged as a new field, and the first images of supermassive black holes (SMBHs) have been captured. A related field, interferometry, has also advanced incredibly thanks to … Read more

Scientists to present the latest in atomic, molecular and optical physics – BIOENGINEER.ORG

Scientists from around the world will present new findings on atoms, simple molecules, electrons and light at the 53rd Annual Meeting of the American Physical Society’s Division of Atomic, Molecular and Optical Physics (DAMOP). The meeting will be held virtually and in person at the Rosen Center Hotel in Orlando, Florida May 30-June 3. Scientists … Read more

Astronomers Witness The X-Ray ‘Fireball’ of a Stellar Nova For The First Time

The brief, yet colossal eruption of a dead star undergoing a new explosion has been captured by one of the most powerful X-ray instruments in space. The joint German-Russian eROSITA telescope, aboard the Spektr-RG space observatory in the L2 Lagrange point (yes, Webb’s home), caught for the first time what is known as the ‘fireball’ … Read more

The era of ‘optical computers’ operated by light is fast approaching – BIOENGINEER.ORG

The demand is explosively increasing for computers that can quickly calculate and process large amounts of information recently, as artificial intelligence, self-driving cars, drones, and metaverse technologies are drawing attention as the core industries of the future. However, electronic semiconductor logic gates, which serve as the brains of computers today, have limited capacities in high-speed … Read more

Ultraprecise Atomic Optical Clocks Could Help Us Redefine The Length of a Second

The definition of a second, the most fundamental unit of time in our current measurement system, hasn’t been updated in more than 70 years (give or take some billionths of a second). But in the next decade or so, that could change: Ultraprecise atomic optical clocks that rely on visible light are on track to … Read more
