2. Long-range optical communication - Wikipedia

   en.wikipedia.org/wiki/Long-range_optical...

   Long-range optical communication or free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking over long distances. "Free space" means air, outer space, vacuum, or something similar.

3. Satellite laser ranging - Wikipedia

   en.wikipedia.org/wiki/Satellite_laser_ranging

   The laser pulse can also be reflected by the surface of a satellite without a retroreflector, which is used for tracking space debris. [1] Satellite laser ranging is a proven geodetic technique with significant potential for important contributions to scientific studies of the earth/atmosphere/ocean system. It is the most accurate technique ...

4. Long-Range Reconnaissance and Observation System - Wikipedia

   en.wikipedia.org/wiki/Long-Range_Reconnaissance...

   Long-Range Reconnaissance and Observation System or LORROS is a sensor system developed by Elbit Systems to provide long-range daytime and night-time surveillance. The unit consists of Forward looking infrared (FLIR) and Charge-coupled device (CCD) image sensors. Optional components include eyesafe laser rangefinder, built-in compass and ...

5. Lidar - Wikipedia

   en.wikipedia.org/wiki/Lidar

   All [citation needed] laser rangefinders, laser altimeters and lidar units are derived from the early colidar systems. The first practical terrestrial application of a colidar system was the "Colidar Mark II", a large rifle-like laser rangefinder produced in 1963, which had a range of 11 km and an accuracy of 4.5 m, to be used for military ...

6. Laser communication in space - Wikipedia

   en.wikipedia.org/wiki/Laser_communication_in_space

   The LLCD is NASA's first attempt at two-way space communication using an optical laser instead of radio waves, and is expected to lead to operational laser systems on NASA satellites in future years. [16] In November 2013, laser communication from a jet platform Tornado was successfully demonstrated for

7. Laser rangefinder - Wikipedia

   en.wikipedia.org/wiki/Laser_rangefinder

   A long-range laser rangefinder is capable of measuring distance up to 20 km; mounted on a tripod with an angular mount. The resulting system also provides azimuth and elevation measurements. A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object.
