Light collection efficiency is an important factor that affects the performance of many optical and optoelectronic devices. In these devices, the high reflectivity of interfaces can hinder efficient ...

Researchers demonstrate a new technique for suppressing back reflections of light, leading to better signal quality for sensing and information technology. Researchers demonstrate a new technique for ...

Waves close wavesVibrations that transfer energy from place to place without the transference of matter. - including sound and light - can be reflected at the boundary between two different materials.

Exploiting a novel technique called phase discontinuity, researchers have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction. The discovery has led ...

Samsung's newly introduced QuantumBlack technology adds a film to the company's QD-OLED panels, enhancing immersion and reducing reflections from external light sources. The South Korean company ...

Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens. of ...

Before diving into ray tracing ("RT" for short), let's first take a look at how illumination works in the real world. From the micro-perspective, the surface of an object illuminated by a ray of light ...
