1. Laser domet nalaznik
The laser rangefinder is an instrument that uses laser to to točno measure the distance the target. When the laser range finder is working, it emits a very thin laser beam to the target, and the photoelectric element receive the laser beam reflected by the target. The timer measures the time from the launch to the reception of the laser beam, and calculates the distance from the observer to the target. Laser domet finder is currently the most widely used range finder, and laser range finder can be classified into handheld laser range finder (measurement distance 0-300 meters), telescope laser range finder (measurement distance 500-3000 meters) .
2. Ultrazvučno udaljenost metar
3. Infrared range finder
An instrument that uses modulated infracrven svjetlo for precise distance measurement, and the measurement range is generalno 1-5} kilometara. The non-diffusion principle of infracrven rays is used: because infracrven rays have a small refractive index when passing through other substances, long-distance rangefinders will consider infracrven rays, and the propagation of infracrven rays takes time. When infracrven rays are sent from the rangefinder When encountering a reflective object, it is reflected back and received by the the rangefinder, and then the distance can be calculated accord to the time from sending out to being received by the infrared ray and the propagation speed of the infrared ray. The advantages of infrared range are cheap, easy to Production, And Safe, And The Disadvantage Is Low Accuracy. , Kratka udaljenost, Poor usmjerenost.
