Laser Rangefinders are tools that use laser beams to measure the distance to an object to be measured. They are used in a wide range of fields, including construction and civil engineering, fisheries, real estate, and railroads. In recent years, applications in the forestry industry have also been promoted. They are characterized by their very high accuracy and ability to measure distances without contact. Depending on the device, some can measure with an accuracy of ±1.0 mm. Since measurement is made using laser light, errors are more likely to occur when there is strong light around or on measurement surfaces made of rough materials.
Laser Rangefinders are used in all kinds of fields because they can measure the distance and height to the object to be measured at the push of a button. For example, they are used in a wide range of construction and civil engineering applications, from measuring the deflection of ceilings and floors to bridge and tunnel maintenance work. In the fishery field, they are used to measure the distance to shore when vessels berth and to measure tidal levels. The forestry field is also used to measure tree height. Recently, laser rangefinders for golf are also available, and some individuals own their own. Further improvements in accuracy are required for control and measurement of aircraft and precision facilities, and the range of applications is expected to continue to expand in the future.
There are two main methods used in laser rangefinding: pulse (propagation time detection) and intensity modulation (phase difference detection). Each method is explained below.
