Holography: Origins, Problems, and Possible Solutions

Most people own at least one hologram, probably without knowing it's a hologram. Those with relatively little optical background, most of the general public, are most likely to encounter real holograms, face to face, in museums, magazines, art galleries, holographic displays, and security devices (such as those on credit cards).

New Filter-Free Imaging Sensors Could Improve Low-Light, Fast Imaging

Newly developed pixel-scale metasurface lenses—flat surfaces that modify light using nanostructures—have been demonstrated to help create imaging sensors that are about three times more sensitive than those now in use. The new sensor architecture may allow digital cameras to image faster or in low-light circumstances.

Color-Sorting Metalenses Boost Imaging Sensitivity

Researchers have shown that newly designed pixel-scale metasurface lenses — flat surfaces that use nanostructures to manipulate light — can be used to make imaging sensors that are roughly three times more sensitive than those used today.

A Nanocomposite Could Help Improve Medical Imaging and Security Screening

A nanocomposite that absorbs X-rays and then, with nearly perfect efficiency, re-emits the captured energy as light, could help to improve high-resolution medical imaging and security screening.

3D Imaging System Created with Optical Fibers Roughly the Width of Human Hair

With fibers roughly the width of a human hair, researchers created a 3D imaging system that holds many potential applications, they say, ranging from remote inspection of small or dangerous machines to a miniaturized and minimally invasive endoscopic tool.

Researchers Come One Step Closer to a Working Optoacoustic Endoscopic Probe

Skoltech researchers and their colleagues have come one step closer to a working optoacoustic endoscopic probe -; a device that could slip inside a blood vessel and analyze atherosclerotic plaques by shining laser light on them to make them wobble like a loudspeaker membrane and betray their chemical composition with an ultrasound signature.

The Viability of Meta-Optics for High-Quality, Full-Color Imaging

Researchers at Princeton University and the University of Washington have developed a full-color nano-camera the size of a grain of salt. 1.6 million cylindrical nano-posts were etched on a silicon nitride layer. A neural image reconstruction algorithm manipulates the morphology of these nano-posts to create wide field-of-view (FOV) full-color images.
