Radio observatories also need to avoid spurious emissions (interference from television and radio stations, radar installations and car ignitions).

We are trying to shoot lasers into the brain.

Using a unique technique for concentrating the solar light, splitting the spectrum to various spectral bands, and using each band for direct optical pumping of different lasers near their emission band resulted in an overall efficiency of 20 per cent.

The clouds are lifting, the sun is breaking through.

He would shoot his light saber across the abyss, making a blade of light, and then scamper across on this blade of light.

Female Voice Long range laser scanning by sending out a pulse that's a laser beam of light.

The laser retroreflector is a passive optical device used as a target by ground based laser ranging stations in order to determine the accurate position of the satellite.1

The second of NASA apos s new techniques for environmental observation was lidar using a laser in a manner similar to radar by bouncing it off objects (e.g. clouds, pollutants, the Earth apos s surface) and then making environmental measurements from the reflected energy.

We studied the acoustics with laser stuff, and they bounce them off this and see where it all works.

The beam splitters and lenses are represented by physical objects, and the system projects down the laser beam path.

At the Andøya Rocket Range, scientific rockets are launched and the international Arctic Lidar Observatory for Middle Atmosphere Research (ALOMAR) facility uses light detection and ranging (lidars) to study the middle and upper atmosphere.

(c) Photo neutron interrogation photo induced neutron emission occurs when the energy of an incoming photon (X ray or gamma ray) is above a certain threshold and atoms of low atomic weight undergo photonuclear reactions that emit neutrons.

Also, the atmosphere has a brightness all of its own, owing in part to scattering of electromagnetic radiation from various sources (such as city lighting, Moon light, auroral type phenomena and lightning).

There you can see mosquitoes as they fly around, being lit up.

Its surface is covered by 426 reflectors to return the laser light back to the observatory.

If placed in close proximity to an object emitting neutrons, or its container, the foil may be activated sufficiently that radio spectroscopy of resulting activation products in the foil could yield low fidelity information on the nature of the neutron flux.

The first is the optical sensor, which reacts to the behaviour of light passing through the test solution, recording such phenomena as the absorption or fluorescence of light, light scattering or spectrophotometry.

We can shoot light into the brain to reactivate the memory of the blue box.

But on this side, it has sugary Gummy Bears, to diffuse the light more slightly.

CNES will provide the altimeter and the Doris system, while NASA will supply the radiometer, the laser reflector and the positioning system.

8 Compute reflected, refracted, and transmitted rays

The Critical Fluid Light Scattering Experiment studied phase transition phenomena near the critical point of the element, xenon.

And we also projected the contents of the time capsule as binary code using a 35 watt laser into outer space.

So what if we could put all that together to shoot them out of the sky with lasers?

Recent advances in the development of directly pumped solar lasers provided new opportunities for the increasing demand for both bandwidth and power for space communication.

Tremendous fire.

They were barefoot, and with each step their toes sank into the muck sending hundreds of flies scattering from the rancid pile.

The enemy used lasers.

Basically, when I look at my partner radiant and confident, probably the biggest turn on across the board.

And in this impossibly beautiful picture, you see the main rings backlit by the Sun, you see the refracted image of the Sun and you see this ring created, in fact, by the exhalations of Enceladus.

In ALOHA 93, a sodium lidar, optical imager, and spectrometer gathered data from an aircraft, the flights being coordinated with selective overpasses of NASA apos s UARS (launched in 1991).

I have solidified the beam of the laser pointer.

Here, we're trying to visualize the airflow around the wings of the mosquito with little particles we're illuminating with a laser.

Light came out of it in every direction.

They were throwing those lights around.

11. The principal instruments on board the satellites include (a) an Active Microwave Instrument (AMI), which comprises a synthetic aperture radar (SAR) and a wind scatterometer (b) a radar altimeter (RA) (c) an along track scanning radiometer (ATSR), which comprises an infrared radiometer (IRR) and a microwave sounder (MWS) (d) precise range and range rate equipment (PRARE), presently functioning only on ERS 2 and (e) a laser retroreflector.

The Institute is a member of the International Laser Ranging Service (ILRS) and the European Laser Ranging Service.

Optical debris can be detected by reflected sunlight when the debris object is sunlit while the ground below is dark.
