Space Lasers Have ‘Bright Future’ in Communications
Neither wind, nor clouds, nor even atmospheric turbulence kept NASA’s Lunar Laser Communication Demonstration (LLCD) from its mission of providing error-free communications to ground stations from lunar orbit, NASA said recently in releasing results of the 30-day experiment. “Throughout our testing we did not see anything that would prevent the operational use of this technology in the immediate future,” said Don Cornwell, LLCD mission manager at NASA’s Goddard Space Flight Center in Greenbelt, Md.

‘Warping’ Compresses Big Data
A physics-based data compression method outperforms existing technologies, such as JPEG, for images and could eventually be adopted for the capture and analysis of massive amounts of data in real time for communication, scientific research and medicine.

Beam Expansion - Standard Concepts Re-interpreted
asphericon GmbH
Everyday work in an optics laboratory would be unthinkable without beam expansion systems. They serve to optimally adjust the beam cross sections between the light sources (e.g. lasers) and the subsequent optical elements. Precise illumination of the optically effective surfaces is essential, especially for beam shaping and focusing with high numerical apertures. The most widespread basic principles of afocal beam expansion systems are based on the telescopes of Kepler and Galileo. In the following article, the various modes of action are revealed in more detail and new approaches based on the use of aspherical surfaces are presented and discussed.
