Superfast camera captures cone-shaped wakes of light

Pulses of light can leave behind cone-shaped wakes of light, somewhat similar tocone-shaped sonic booms created byaircraft flying at supersonic speeds. Now, a superfast camera has captured the first-ever video of these events. To capture video of these elusive light-scattering events, the researchers developed a “streak camera” that could capture images at speeds of 100

Fiber optic testing

Fiber optic cable in essence, is a hair-like glass conduit that carries virtually any type of signal from one point to another at light speed (at the speed of light has in glass, around two thirds of the speed it has in free space). Today, practically every communication network contains fiber optics, because fiber’s extra

Fiber optics technology

An optical fiber is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter typically slightly thicker than that of a human hair. Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications. Fibers are
