Terahertz radiation — the band of electromagnetic radiation between microwaves and visible light — has promising applications in security and medical diagnostics, but such devices will require the ...

This week has been laser week at the Defense Advanced Research Projects Agency, with two very different laser-based programs hitting major milestones: an inexpensive array of lasers on a single chip ...

For many centuries, the principle of triangulation - that is the geometric measurement using three-point relationships - has been relatively well known. In Europe, the land survey method established ...

PLYMOUTH, Minn., Jan. 4, 2015 /PRNewswire/ — Vixar announces a family of high power Vertical Cavity Surface Emitting Laser (VCSEL) arrays targeting consumer, medical, industrial and automotive ...

A compact galvanometer laser scanner developed by Fraunhofer ILT has been designed to suit new applications in 3D printing, micromachining or medical technology. The scanner occupies only 50 cubic ...

Principles of supersymmetry have been used to boost the performance of an array of solid-state lasers. The work was led by Mercedeh Khajavikhan at the University of Central Florida in the US. Her team ...

The development of monolithic arrays of high-power, single-mode semiconductor lasers is set to bring big benefits to the printing, coding and marking industries. Printing is arguably one of the most ...

Microarrays are nothing without their scanners, the instruments that extract the array's data in computer-readable form. Steve Fodor and colleagues at Affymax built the first scanner in 1989, around ...
