Scientists Propose Removing Space Debris from Orbit with Fiber Optic Laser

An international team of scientists have put forward a blueprint for a purely space-based system to solve the growing problem of space debris. The proposal, published in Acta Astronautica, combines a super-wide field-of-view telescope, developed by RIKEN’s EUSO team, which will be used to detect objects, and a recently developed high-efficiency laser system, the CAN laser that was presented in Nature Photonics in 2013, that will be used to track space debris and remove it from orbit.

Elemental LED Introduces SWITCHEX that Combines LED Dimmer Switch and LED Driver into a Single Unit

Elemental LED, a Bay Area LED manufacturer introduces SWITCHEX, the next step in LED control to its Diode Led product line. SWITCHEX combines an LED dimmer switch and LED power supply into a single integrated unit. The SWITCHEX Dimmer-Driver accepts 120 Volt AC and converts it to low voltage DC, all within a standard electrical box. With power options up to 100W, it is a true evolutionary step forward for power and control of LED applications.

Light Demonstrates Angular Acceleration When Traveling Along a Helical Path

Light must travel in a straight line and at a constant speed, or so the laws of nature suggest. Now, researchers at the University of the Witwatersrand in Johannesburg have demonstrated that laser light traveling along a helical path through space, can accelerate and decelerate as it spins into the distance.
