An optical laser reads the transparency and creates a wobbly, out-of-tune, almost eerie-sounding keyboard effect.
Next year, NASA is to launch a demonstration mission to test optical laser communications in conjunction with the LADEE (Lunar Atmosphere and Dust Environment Explorer) mission to the moon.
FORBES: Future Of NASA's Aging Deep Space Network Lies In X-Rays And Lasers
The new technology places glass optical fibers, which contain a laser diode that sends a signal beam into the optical, into the flutes.
And an optical mission to test laser relay capabilities from earth geosynchronous (GEO) orbit will soon follow.

It s the leader in expensive high-end positioning technologies, including GPS, laser and optical systems for the military, aviation, surveying, mapping and construction.
Lucent's 30, 000 techies work on such advances as plastic fiber flexible enough to wire your home, a new over-the-air laser system for local optical transmission and routers with mind-boggling capacity.
Electrical engineers at Stanford University have created nanoscale optical lines that use much less power than the laser connectors found in computers today.
It is the world's most powerful optical sensor, achieving up to 6400 dpi resolution without sacrificing the natural tracking feel of an optical sensor or yielding the robotic sensation of a comparable laser option.

All-optical switches use micromirrors, which were originally developed to bounce laser beams around the surface of a silicon chip.
Moreover, engineers have worked out how to make laser beams more intense by using short lengths of optical fibre to narrow the beam.
With mobeam's technology, the Galaxy S4 can "beam" traditional 1D barcode data to any laser scanner with no new equipment, such as optical scanners or backend systems, required by the retailer.

This generates the coherent light of a laser beam in the core of a long, thin optical fibre.
Researchers at the University of Bristol, for instance, are focusing their experiments on photons, containing them in small optical fibers that are built onto integrated chips with the help of a laser trap or ion trap.
FORBES: Teeny-Tiny Quantum Computers Take A Step Closer To Reality
One is an adaptation of a well-known effect called "optical tweezers" in which objects can be trapped in the focus of one or two laser beams.
