Overview 5 kinds of laser rangefinders best: the characteristics, pros and cons

Laser rangefinder - processing device for determining distances by means of a laser beam. The models are divided into pulse and phase.

Principle of operation

pulse . The basis of the principle of put a constant speed of light. Knowing the time of the path is calculated the distance to the desired object. Luminous flux is supplied in short pulses.

phase . The operation of the luminous flux is changed property phase modulation (simplified - the parameters of the oscillations) upon reflection from the object. The distance is calculated based on a processor of measurements.

Measurement accuracy ± 0.5 mm, which is comparable with the magnitude of the low-frequency light waves. Have low power, the measurement range of not more than 1 km. Devices are cheap enough. The basic direction - the use in consumer devices.

Types of devices:

• rangefinder household;
• rangefinder, binoculars;
• hunting device;
• device for the machine;
• building level with a laser sight;
• rangefinder, monocular;
• laser rangefinder inexpensive;
• rangefinder roulette;
• rangefinder with a protractor.
