Satellite Laser Ranging (SLR) is currently the unique technique to determine station coordinates, Earth Orientation Parameters (EOPs) and Stokes coefficients of the Earth’s gravity field from one observation equation with a high accuracy. These parameters form the so-called ‘three pillars’ (Plag and Pearlman, 2009) of the Global Geodetic Observing ...

Usage of lasers as sources of light narrow-beams in beacons considerably increases of detectable distances in area of large optical thickness in dense atmospheric smokes, when traditional lights are not so visible. On the one hand, it is reached due to a high directivity of the laser beams, and with other high spectral brightness and concerning high ...

Coherent-burst laser ranging: decoupling resolution and unambiguous range
Optics Letters, 1997A novel signal encoding and decoding method for laser ranging is proposed and experimentally demonstrated. The coherent-burst method uses a quasi-continuous interrupted burst of modulated laser radiation to achieve high-precision ranging at all distances.

Determining the range to a satellite in orbit around the earth utilising the technique of satellite laser ranging (SLR) was pioneered in the early 1960s. The first successful ranging experiment was reported in the 3 December 1964 issue of Flight International (Smith 1964). Dr. Henry H. Plotkin of Goddard Space Flight Centre led a NASA team to track the

The conventional method used to detect the range to an underwater object is by sending and receiving some form of acoustic energy. However, acoustic systems have limitations in the range resolution and accuracy they can provide under certain conditions.

Scannerless laser range camera
Sensor Review, 1999The requirement to quickly obtain 3D measurements is common to a variety of tasks in different fields of applications, i.e. robotics, space craft rendezvous and docking scenarios and industrial assemblies. In this paper, a novel type of non‐scanning optical 3D laser camera is presented.

Automatic Laser Tracking and Ranging System
Applied Optics, 1971An automatic laser tracking and ranging system has been developed for use with cooperative retroreflective targets. Target position is determined with high precision at ranges out to 19 km and sample rates up to one hundred measurements per second. The data are recorded on a magnetic tape in the form of azimuth, elevation, range, and standard time and ...

A novel signal encoding and decoding method for laser ranging is described. The coherent burst method achieves high precision ranging based on simultaneous analysis of time-of-flight and phase shift of an amplitude modulation pattern that is electronically coherent with a master oscillator.

The Army uses lasers to measure the distance to a target, to mark a target for laser-guided weapons or to simulate direct-fire weapons in tactical training. These systems are respectively called laser rangefinders (LRFs), laser target designators (LIDs), or laser direct-fire simulators (LDFSs). There are devices that perform both fire control functions
