Qhov txawv ntawm ultrasonic range finder thiab laser range finder
1. Hais txog qhov tseeb, qhov ntsuas qhov tseeb ntawm ultrasonic rangefinder yog nyob rau theem centimeter, thiab qhov ntsuas qhov tseeb ntawm lub laser rangefinder yog nyob rau qib millimeter;
2. Nyob rau hauv cov nqe lus ntawm kev ntsuas ntau, qhov ntsuas ntau ntawm ultrasonic rangefinder feem ntau yog nyob rau hauv 80 meters, thaum lub sij hawm ntsuas ntawm lub handheld laser rangefinder tuaj yeem ncav cuag li 200 meters, thiab qhov ntsuas ntau ntawm lub laser rangefinder telescope tuaj yeem ncav cuag ntau pua. kilometers. Txawm nyob deb npaum li cas (qhov kev ntsuas qhov tseeb ntawm laser qhov tsom iav feem ntau yog 1 meter lossis kaum centimeters).
3. Lub ultrasonic range finder yog ib qho yooj yim los qhia qhov yuam kev. Txij li thaum lub ultrasonic range finder emits suab nthwv dej thiab muaj cov kiv cua-zoo li emission yam ntxwv ntawm lub suab tsis, thaum muaj ntau yam teeb meem nyob qhov twg lub suab tsis dhau, yuav muaj ntau reflected suab nthwv dej, ntau cuam tshuam, thiab qhia yuam kev. Lub laser rangefinder yog ib lub teeb me me ntawm lub teeb laser uas tau tawm thiab rov qab los, yog li ntev npaum li lub nqaj tuaj yeem dhau mus, yuav luag tsis muaj kev cuam tshuam.
4. Tus nqi ntawm ib qho ultrasonic rangefinder ranges los ntawm kaum tawm yuan mus rau ob peb puas yuan, thiab tus nqi ntawm ib tug laser rangefinder ranges los ntawm ob peb puas yuan mus rau ob peb txhiab los yog kaum txhiab yuan, nyob ntawm qhov raug thiab nyob deb.
