Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The ...

By replacing bulky lenses with software-driven sensor arrays, the researchers unlock a new era of flexible, high-resolution ...

Diffraction spikes, visible in high-power astronomical images, are an intrinsic optical phenomenon in reflecting telescopes, primarily caused by the diffraction and subsequent interference of incoming ...

Researchers at Harvard University and Jiangsu University developed a technique for not only identifying infected cells, but also tracking the infection over time as the cells developed. They published ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

Optics meets 2D materials: a simple probe light beam exiting an optical moiré lattice can be chopped up into diffuse streaks or confined into a single bright spot, depending on the twist angle in the ...

Corner cube retroreflectors (CCRs) consist of three mutually perpendicular intersecting flat surfaces that directly reflect incident light back to its source 1, 2. The incident light is internally ...

Most large-sensor cameras use a Bayer colour filter pattern to allow full colour images to be output - after "debayering". This entire process is now pretty routine but unfortunately what is also ...

Two become one: various diffraction patterns showing Rayleigh's criterion. (Credit: Wikimedia Commons/Spencer Blevin) Scientists have long believed that diffraction limits the minimum distance that ...
