Laser rangefinder inoshanda sei?

Laser rangefinders, seyakanyanya kurongeka uye yekumhanyisa kuyera chishandiso, shanda zviri nyore uye nemazvo. Pazasi, isu tichakurukura zvakadzama kuti laser rangefinder inoshanda sei.

1. Laser Emission Basa relaser rangefinder rinotanga nekubuda kwelaser. Mukati me laser rangefinder mune laser transmitter, iyo ine basa rekuburitsa pfupi asi yakanyanya laser pulse. Iyo yakakwira frequency uye pfupi pulse hupamhi hweiyi laser pulse inoita kuti isvike kune chainotarirwa chinhu munguva pfupi pfupi.

2. Laser reflection Kana laser pulse ikarova chinhu chakanangwa, chikamu chelaser simba chinotorwa nechinhu chakanangwa uye chikamu chelaser mwenje chinoratidzwa kumashure. Iyo inoratidzwa laser danda inotakura ruzivo rwechinhambwe nezvechinhu chakanangana.

3. Laser reception Iyo laser rangefinder inewo inogamuchira mukati kuti igamuchire inoratidzwa laser beam. Uyu anogamuchira anosefa kunze kwechiedza chisingadiwe uye anogamuchira chete anoratidzwa laser pulses anoenderana nelaser pulses kubva kune laser transmitter.

4. Chiyero cheNguva Kana mugamuchiri angogamuchira inoratidzwa laser pulse, yakanyatsojeka timer mukati melaser rangefinder inomisa wachi. Iyi timer inokwanisa kunyatso nyora musiyano wenguva Δt pakati pekutumira uye kugamuchirwa kwe laser pulse.

5. Distance Calculation Nenguva yakasiyana-siyana Δt, laser rangefinder inogona kuverenga kureba pakati pechinhu chinotarisirwa uye laser rangefinder kuburikidza nemaitiro akareruka emasvomhu. Ichi chinyorwa ndechekuti: kureba = (kumhanya kwechiedza × Δt) / 2. Sezvo kukurumidza kwechiedza kunozivikanwa nguva dzose (anenge makiromita 300,000 pasekondi), kureba kunogona kuverengwa nyore nyore nekuyera nguva yakasiyana Δt.

Laser rangefinder inoshanda nekufambisa laser pulse, ichiyera musiyano wenguva pakati pekutapurirana kwayo uye kugashira, uyezve kushandisa chigadzirwa chekumhanya kwechiedza uye musiyano wenguva kuverenga chinhambwe pakati pechinhu chakanangana neiyo laser rangefinder. Iyi nzira yekuyera ine mabhenefiti ehupamhi hwepamusoro, kumhanya kwakakwira uye kusabatika, izvo zvinoita kuti laser rangefinder ishandiswe zvakanyanya munzvimbo dzakasiyana siyana.
