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 ...

PITTSBURGH (KDKA) -- On really hot days, you may hear a meteorologist tell you to wear light colored clothing. Why is this? Well, it is all because of thing called "Albedo". Albedo is how reflective a ...

THE author pointed out that most previous experimenters, A especially Rood, had measured the amount of the transmitted light, and that any percentage of error in this ...

Improving the efficiency of photovoltaic cells is one of the great challenges for renewable energy science. In the lab, the best cells can convert almost half the sunlight hitting them into ...

Manufacturers are adopting automated optical inspection (AOI) systems based on phase shift profilometry (PSP) for applications in advanced packaging processes. Many of these processes use front ...

Silvery fish such as herring, sardine and sprat have evolved special skin that gets around a basic law of physics, according to new research. Reflective surfaces polarize light, a phenomenon that ...

The effect is known from the smart phone: Sun is reflected by the display and hardly anything can be seen. In contrast to this, the glasswing butterfly hardly reflects any light in spite of its ...
