Telémetro de caza Tiro con arco
La precisión del telémetro láser depende principalmente de la precisión del cálculo del tiempo de envío y recepción del láser. De acuerdo con la tecnología adoptada y las ocasiones de aplicación, los telémetros láser se pueden dividir en telémetros láser convencionales (utilizados principalmente para deportes al aire libre, caza, etc.), con una precisión de aproximadamente 1 m, y telémetros láser de alta precisión para topografía y mapeo, topografía, construcción, aplicaciones de ingeniería, militares, etc.
Phase method rangefinder is a rangefinder that modulates the laser phase and obtains the distance by measuring the phase difference of the reflected laser. Because the reflected laser phase needs to be detected, the received signal needs to have strong intensity. Considering the safety of human eyes, telescope systems such as pulse laser rangefinder can not be used, and the range is small. The typical ranging range is 0.5mm to 150m. Generally speaking, the phase laser rangefinder adopts 635 nm (red vision) laser as the debugging object, commonly known as infrared rangefinder. However, the definition of laser is not based on color. If 635 nm laser rangefinder is used to directly irradiate human eyes, it will cause irreversible damage. Please use and protect correctly.
Because the propagation speed of ultrasonic wave in the air is greatly affected by temperature, humidity and air pressure, the measurement error is large. Due to the long wavelength and short propagation distance of ultrasonic, the measurement distance of general ultrasonic rangefinder is short and the measurement accuracy is low. However, as a fan, ultrasonic transmission has more characteristics than photoelectric rangefinder. It is widely used in safety protection, cable height measurement, obstacle detection and other fields.
El telémetro láser ha sido ampliamente utilizado en energía eléctrica, conservación del agua, comunicación, medio ambiente, arquitectura, geología, policía, protección contra incendios, voladuras, navegación, aviación, ferrocarril, contraterrorismo / militar, agricultura, silvicultura, bienes raíces, ocio / deportes al aire libre y otros campos.
