What is Laser Rangefinder?

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 target and returned to the sender. 
Due to the high speed of light, this technique is not appropriate for high precision sub-millimeter measurements, where triangulation and other techniques are often used. It is a type of scannerless lidar.

The Principle of Laser Rangefinder

A laser rangefinder is an instrument that uses a laser beam to measure distance.
The basic principle is to emit laser pulses to the object to be measured and start timing, and stop timing when the reflected light is received.
This time can be converted into the distance between the laser and the target.
Laser rangefinders can also emit multiple laser pulses to determine whether an object is moving away from or approaching the light source through the Doppler effect.
 

What does a Laser Rangefinder Do?
An LRF or Laser Rangefinder is a device used to measure precise distances. Most laser rangefinders operate on the time of flight principle by sending a laser pulse in a narrow beam towards the object.

• What is a Laser Rangefinder Used For?
  Laser rangefinders can be used to monitor or measure distances or object lengths. They can also provide positional locations over long distances, e.g. several kilometers, without physically touching the observed object. The laser range finders are regularly used in geodesy, sports, hunting or military.
   
• How Does a Laser Rangefinder Work?
  Most laser rangefinders operate on the time of flight principle by sending a laser pulse in a narrow beam towards the object. A receiver then detects the reflection of that light and accurately calculates the distance based on the time it took for the light to bounce back.
   
• Is A laser Rangefinder Accurate?
  There are two ways to use the laser rangefinder: the pulse method and the phase method. Pulse-emitting laser rangefinders generally have low absolute accuracy, but long-range measurements can achieve good relative accuracy; 1mm.
