A new lens-free imaging system uses software to see finer details from farther away than optical systems ever could before.

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of ...

(Nanowerk Spotlight) Perovskite materials have attracted great attention in the fields of optoelectronics due to their significant optoelectronic properties. So far, the applications of perovskite ...

Multipixel-array (MPA) sensing for target detection within specific distances combines the benefits of background suppression, sharply defined sensing, and insensitivity to object color with the ...

Some motion sensors are based on optical measurement technologies to provide accurate velocity and position measurements without requiring physical contact with the object or surface being monitored.
