A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the ...
Length measurement, distance measurement, or range measurement (ranging) refers to the many ways in which length, distance, or range can be measured. The most commonly used approaches are the rulers, followed by transit-time methods and the interferometer methods based upon the speed of light .
Lunar Laser Ranging (LLR) is the practice of measuring the distance between the surfaces of the Earth and the Moon using laser ranging. The distance can be calculated from the round-trip time of laser light pulses travelling at the speed of light, which are reflected back to Earth by the Moon's surface or by one of several retroreflectors ...
Triangulation is a method for distance measurements, often using a laser. It exploits the ability of a laser beam to propagate in a well- collimated form (i.e. with small beam divergence) over large distances.
19 lut 2019 · I was with the Leica Geosystems in 1993 when we introduced the first Laser Distance Meter (LDM) at the Batimat show in Paris. Like a 1993 cell phone, the first Leica DISTO was the size of a brick and weighed about the same.
26 wrz 2021 · The article presents methods of long range distance measurements using pulsed lasers and the Time of Flight principle. Various algorithms of laser distance measurements with digital acquisition of echo pulses (acquisition of a signal’s full waveform) are presented.
25 kwi 2017 · A laser distance meter works by use measuring the time it takes a pulse of laser light to be reflected off a target and returned to the sender. This is known as the "time of flight" principle, and the method is known either as “time of flight” or “pulse” measurement.
