Rangefinders are a device used to measure the distance between the observer to his target. Several types of ranging devices are introduced till now, and each has a different technique to measure the distance.
With the introduction of the rangefinder, it has been used for targeting distant objects. It has helped the military person during Second World War and soldiers for targeting their enemies and killing them.
The engineers are introducing new ranging techniques by enhancing the performance of the devices. Today devices are used in various fields for example used in golfing, hunting and for measuring construction sites.
Today, one can buy these devices at affordable prices, and different high tech Rangefinder is available for standard users.
These ranging devices were not easily purchased in the past and were only available for army personnel. Later, some companies introduced some more ranging devices with new techniques.
The Brief history about the golf rangefinders:-
Since the introduction of the first rangefinder, the ranging technology has evolved and the necessary type of rangefinder Stroud in the 1880s developed by Scottish company Barr. Earlier, the device was the basic version of a ranging device, which later evolved and turned into a very essential ranging gadget.
The optical range finder is usually classified into two kinds, coincidence and stereoscopic.
The coincidence rangefinders were used in cameras which were used for surveillance and surveying. The device consists of an eyepiece located at the center and lens and prisms on both ends of the devices.
Parallax is used to correct the position to view the object and estimating their distance. By calculating angle created by the line of sight at both the ends, ranges of the object can be determined.
If the object is located at the best altitude then the edge will be depicted to be smaller and if the angle is extensive then the object seems to be much more closer than before. These types of devices were used during second world war by the armies.
Invention of the laser golf rangefinder
During the early 20th century many experts were working on the laser technology, and those looking for a better technology have introduced the first laser rangefinder in 1965.
All the coincidence ranging devices were replaced by the laser rangefinders as laser rangefinders were capable of providing perfect measurement in comparison to coincidence rangefinders. It is also applied in numerous military techniques.
Presently devices with laser technology is applicable in numerous fields like hunting, construction, golfing and many more.
Laser rangefinder ranging technology is very similar to the radar technology. The radar emits electromagnetic waves and receives the reflected waves from the objects and calculates the distance by evaluating the time taken. The laser rangefinder applies the same logic, but instead of electromagnetic waves, it emits laser beams.
