A laser range finder measures precise distances.
Understanding Laser Range Finders
A Laser Rangefinder (LRF) is a specialized device designed to accurately determine how far away an object is. According to the reference provided, its primary function is to measure precise distances.
How It Works
Most laser rangefinders operate using a principle known as "time of flight." This involves:
- Sending a laser pulse towards an object.
- Measuring the time it takes for the pulse to travel to the object and reflect back to the rangefinder.
- Calculating the distance based on this elapsed time and the known speed of light.
By using a narrow laser beam, these devices can pinpoint specific targets and measure distances with high accuracy, making them valuable in various applications.
Key Function
In simple terms, the core measurement provided by a laser range finder is:
- The distance between the user (or the device) and a targeted object.
This precise measurement is achieved by utilizing laser technology and the time-of-flight method described.
