Definition and Basic Function

A Laser Rangefinder Module is a sophisticated device designed to measure the distance from the device to a target using laser technology. These modules are integral in various fields due to their precision and reliability. By emitting a laser beam and calculating the time it takes for the beam to return after reflecting off a target, these modules provide accurate distance measurements essential for numerous applications.

An LRF or Laser Rangefinder Module For Electro Optical System 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.

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. Some higher end laser rangefinders are able to achieve millimeter-level precision, even over long distances.

For more information on how an LRF functions, see our whitepaper on LRF Performance: Ranging Limitations of Laser Range Finders.
