Rangefinder binoculars are telescopes equipped with distance measuring capabilities and are commonly used to measure the distance to distant targets. Based on different working principles and technologies, rangefinder binoculars can be classified into the following categories:
Laser rangefinder binoculars use a laser beam emitter to send out laser pulses and calculate the target distance by measuring the round-trip time of the laser pulses. These binoculars typically offer high precision and a longer range for distance measurement, making them suitable for measuring targets at longer distances.
Parallax rangefinder binoculars utilize the parallax effect of human vision to measure target distance. They usually have two viewing points and calculate the target distance by observing the positional difference of the target between the two viewpoints. Parallax rangefinder binoculars are suitable for measuring targets at relatively close distances.
Hydraulic rangefinder binoculars use a hydraulic system to measure target distance. These binoculars typically calculate the target distance by measuring the position of the piston in the hydraulic system. Hydraulic rangefinder binoculars are suitable for measuring stable targets.
Oscillation rangefinder binoculars measure target distance using oscillation or vibration. They calculate the target distance by measuring the frequency of oscillation or the amplitude of vibration. This type of binoculars is commonly used for measuring distances on the ground or to buildings.
These are several common classifications of rangefinder binoculars. Each type of rangefinder binoculars has its specific working principle and application field. When selecting a rangefinder binoculars that suits specific needs, factors such as measurement range, precision requirements, and usage environment can be taken into consideration.
