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

This is actually a light emitter.

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

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

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 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.

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

We are trying to shoot lasers into the brain.

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.

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.

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

. In future space missions, lasers, especially very small, lightweight semiconductor emitters, would often be incorporated into standard attitude control instruments and into scientific payloads.

An example of this is ground and space based kinetic energy and laser weapons.

The directed energy weapon is mainly an airborne laser (ABL).

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

It disposes of an ultra precise Satellite Laser Ranging System (SLR), a permanently recording Global Positioning System (GPS) receiver, a radar altimeter transponder, software expertise for GPS, laser and altimetry data reduction and processing.

Your Blu ray player has a very cheap blue laser.

Based on the orbital experience of TUBSAT A and TUBSAT B, launched in 1991 and 1994, respectively, instrumentation of the third spacecraft will also include three fibre optic laser gyroscopes.

The system is composed of a Nd Yag laser, a light beam expander, a telescope, a CCD camera, a photo multiplier and a computer.

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.

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

So this robot is actually equipped with a camera and a laser rangefinder, laser scanner.

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

. Major efforts in the development of space based laser systems were devoted to remote sensing instrumentation.

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

And this is very important light to capture, because this is the light that reflects off the first surface of the skin.

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.

Smooth surfaces result in specular reflection with practically all of the signal being reflected away from the sensor.

A. Use of space based lasers in remote sensing, communications and instrumentation

Now, let's see the surfaces according to the quality of light that they reflect.

They take all the parallel incoming rays and focus it to a single spot.

What you see here is a jungle scene, and you see the surfaces according to the amount of light that those surfaces reflect.

The seismic sources would be launched in the same way as the penetrators.

These systems would require such advanced sensor technologies as focal plane arrays and laser radar.

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

The x ray absorption spectroscopist's periodic table

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

SUNSAT would also carry the global positioning system (GPS) navigational receiver of the National Aeronautics and Space Administration (NASA) and a set of laser reflectors for precise positioning experiments.

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

Efforts are also being made to improve satellites and launchers in terms of design, launching technique and reliability.
