Five periods of measurement with lidar instruments were carried out in 1994.

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.

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.

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

1.2.2 Radar and optical measurements from space

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.

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).

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.

The laser radar system for detecting space debris has been investigated by an ISAS group led by T. Yokota.

For example, the lidar system compiled a complete map of lunar elevations, discovering a 12 kilometer deep impact crater at the lunar south pole in the process.

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

In fact, the application of light detection and ranging (lidar) instruments was considered an extremely promising new way of obtaining essential atmospheric and geophysical parameters on a global scale.

The payloads of the satellite segment of both systems would be designed to monitor the land and ocean environment, the geosphere, hydrosphere and meteorological conditions, with the aid of visible, near infrared, microwave, short wave and thermal radiometers, synthetic aperture radar, radar altimeter and scattering lidar.

The new ALOMAR lidar observatory for middle atmosphere observations, particularly for continuous ozone measurements, is the object of a great deal of international interest.

For radar measurements, the signal intensity return is inversely proportional to the fourth power of distance since radars must provide their own illumination.

Under the Coupling, Energetics, and Dynamics of Atmospheric Regions (CEDAR) program, scientists at the University of Tennessee, Urbana, organized a campaign referred to as ALOHA 93 (Airborne Lidar and Observations of the Hawaiian Airglow).

By contrast, radar satellites, such as the ERS 1 and 2, JERS and Radarsat, exploited the microwave region of the spectrum.

An advantage of optical measurements over radar measurements is that the signal intensity from reflected sunlight falls off only as the square of the distance or altitude, whereas the radar signal return falls off as the fourth power of distance.

The enemy used lasers.

Specifically, the said capabilities include among others Solar Activity Model and Atmospheric Global Circulation Model, Meteoroid Environment Model, measurement instruments (e.g. Meteor Wind Radar, MF Radar, Wind Profiling Radar, Bounder Layer Radar, optical telescopes) and a number of scientists who have experience in developing models.

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

Optimum Power Calibration failed.

Today, a plastic unit smaller than a compact disc can be purchased for as little as US 3, and thousands can be deployed in a few hours.

And then the laser actually cuts.

Remote sensing of space debris from ground based measurements generally falls into two categories radar measurements and optical measurements.

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

Within the project ENVISAT considerable efforts were undertaken to implement multi colour laser ranging, which should improve laser accuracies by eliminating influences of the dry part of the troposphere.

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

Information derived from imaging radar, such as synthetic aperture radar (SAR), is very different from that obtained from optical sensors, since an SAR is particularly sensitive to the geometrical characteristics of the surface and the object being monitored as well as to their dielectric properties.

Your Blu ray player has a very cheap blue laser.

And we also use three laser range finders.
