European XFEL, the biggest X-ray laser in the world, has generated its first X-ray laser light. The X-ray light has a wavelength of 0.8 nm -- about 500 times shorter than that of visible light. At ...

Microlens array-based light-field imaging has been one of the most commonly used and effective technologies to record high-dimensional optical signals for developing various potential high-performance ...

Since it was invented decades ago, ray tracing has been the holy grail for rendering computer graphics realistically. By tracing individual light rays as they bounce off multiple surfaces, it can ...

A well-known defect introduced during the fabrication of GRIN lenses can be exploited for the creation, detection and wave-guiding of exotic forms of vectorial structured light, bringing the toolkit ...

Unless you're a physicist, you probably don't pay too much mind to the function of light in your daily life. Light is light, right? When there is light, we see, and when there isn't, we don't. But ...
