Wprowadzenie do funkcjonalne charakterystyka faza metoda dalmierz
Under given modulation and standard atmospheric conditions, the frequency c/(4 π f) is a constant, and the measurement of distance becomes the measurement of the number of half wavelengths included in the measuring line and the measurement of fractional parts less than half wavelengths, i.e. N or φ, Due to the development of modern precision machining technology and radio phase measurement technology φ The measurement has achieved high accuracy.
W zamówienie do pomiar faza kąt z mniej niż π φ, Różne metody can be used for measurement, and the most commonly used methods are delay phase measurement and digital phase measurement. Currently, short range laser range use the principle of digital phase measurement to obtain φ.
As mentioned above, in general, phase laser ranging uses a continuous laser beam with modulated signals. In order to achieve high ranging accuracy, cooperative targets need to be configured. The currently launched handheld laser rangefinder is another new type of rangefinder among pulse laser rangefinders, which is not only small in size and light in weight, but also uses digital phase measurement pulse broadening and subdivision technology. Without the need for cooperative targets, millimeter level accuracy can be achieved, and the measurement range has exceeded 100m, And it can quickly and accurately display the distance directly.
Środki ostrożności kiedy używanie a laser dalmierz
Uwaga kiedy użycie a laser dalmierz: laser dalmierz nie może być celowany na człowiek oko dla bezpośredniego pomiaru do zapobiegania szkodzie do człowieka ciała. Tymczasem % 2c ogólny laser dalmierze nie nie mieć wodoodporny funkcje % 2c tak to jest konieczne do zwrócić uwagę na hydroizolację. The latest American Leopold laser rangefinder is mainly suit for outdoor hunting enthusiasts in the United States, so the advantage of it production is that it can be waterproof and fogproof, and is equipped with colorful jungle tree branches and leaves.
A laser robi nie mieć funkcja of zapobieganie upadek, so laser dalmierz jest łatwe to uszkodzenie oświetlacz.
Laser dalmierz konserwacja:
③ This machine is a high-precision instrument that integrates optics, mechanics, and electronics. It should be handled with care during use and is strictly prohibited from squeezing or falling from a height to avoid damaging the instrument.
