Laser Distance Measuring InstrumentsPhase thiab Pulse Method Laser Distance Measuring Technology Principles
4x Zoom Digital Sight, 2. Digital Sight tso cai rau koj tsom mus rau cov hom phiaj nyob deb sai dua thiab tuaj yeem siv rau hauv qhov chaw zoo nkauj sab nraum zoov. Nyob rau hauv ib puag ncig uas lub laser dot yog indistinguishable rau qhov muag liab qab, koj tuaj yeem yooj yim txheeb xyuas lub laser dot ntawm qhov loj 2.4-inch siab-txhais xim zaub thiab raug ntsuas qhov ntev.
Laser rangefinder, yog siv cov kev hloov kho ntawm ib qho kev ntsuas ntawm lub laser kom ua tiav qhov kev ntsuas qhov deb ntawm lub hom phiaj ntsuas, nws yog lub teeb yuag, me me, yooj yim rau kev khiav lag luam ceev thiab raug, thiab nws qhov yuam kev tsuas yog ib feem tsib mus rau ntau pua. los ntawm lwm yam optical rangefinders. Lub ntiaj teb thawj lub laser, los ntawm Teb Chaws Asmeskas Hughes Aircraft Corporation kws tshawb fawb Mayman hauv xyoo 1960, thawj qhov kev vam meej ntawm ruby laser. Cov tub rog Asmeskas sai sai tau tshawb fawb txog cov khoom siv laser ntawm lub hauv paus no. 1961, thawj lub laser rangefinder los ntawm US tub rog ua qauv qhia, ntawm lub laser rangefinder sai sai tom qab ntawd nkag mus rau theem ua tau zoo. Raws li cov nqi laser rangefinder txuas ntxiv poob, kev lag luam tau maj mam pib siv laser rangefinders. Nyob rau hauv tsev thiab txawv teb chaws tau tshwm sim ib tug xov tooj tshiab nrog ceev nyob deb ntsuas, me me, txhim khu kev qha kev ua tau zoo thiab lwm yam zoo ntawm miniature rangefinder, yuav tau lug siv nyob rau hauv industrial ntsuas thiab tswj, mining, ports thiab lwm yam teb.
Lub hauv paus ntsiab lus ntawm theem txoj kev laser deb ntsuas tshuab:
Lub mainstream laser rangefinder nyob rau hauv kev ua lag luam niaj hnub no yog raws li theem txoj kev ntawm laser rangefinder. Qhov no yog vim hais tias lub laser rangefinder raws li theem txoj kev tuaj yeem yooj yim kov yeej lub ultrasonic rangefinder ib qho kev tsis txaus siab: loj dhau qhov yuam kev, kom qhov ntsuas qhov tseeb mus rau qib millimeter. Lub ntsiab drawbacks ntawm laser rangefinders raws li txoj kev no yog lub complexity ntawm Circuit Court, luv luv nrug (kwv yees li ib puas metres, tom qab kev siv zog ntawm ntau tus kws tshawb fawb, tam sim no kuj muaj theem txoj kev laser rangefinders nrog ib tug deb ntawm ob peb puas meters).
Theem txoj kev laser deb ntsuas tshuab, yog siv lub xov tooj cua zaus laser, amplitude modulation thiab sinusoidal modulation ntawm lub teeb round-trip rangefinder thiab qhov kev ncua deb ntawm lub hom phiaj uas ua los ntawm cov theem sib txawv ntsuas, raws li lub modulation ntawm lub wavelength thiab zaus ntawm lub teeb. , kev hloov dua siab tshiab ntawm lub sij hawm laser ntawm lub davhlau, thiab tom qab ntawd xam qhov kev ncua deb yuav tsum tau ntsuas nyob rau hauv lem. Cov txheej txheem feem ntau yuav tsum tau muab tso rau ntawm daim iav ntawm cov khoom yuav tsum tau ntsuas, lub laser yuav tsum reflected rov qab mus rau lub laser rangefinder nyob rau hauv thawj txoj kev, los ntawm lub receiver module ntawm lub discriminator kom tau txais kev ua. Nyob rau hauv lwm yam lus, txoj kev yog ib tug passive laser nrug ntsuas tshuab nrog kev koom tes lub hom phiaj.
Lub hauv paus ntsiab lus ntawm pulse method laser rangeing technology:
Theem txoj kev zoo ib yam li cov qauv siv nyob rau hauv ultrasonic ceev xws li, qhov siab tshaj plaws ntsuas qhov deb yog feem ntau yog ob peb puas metres, tuaj yeem yooj yim dua mus txog qhov kev txiav txim millimeter ntawm qhov loj, tab sis raws li tus qauv tsim ntawm qhov rangefinder qhov siab tshaj qhov ntsuas qhov deb yog txwv, tsis scalable. Txoj kev no yog siv nyob rau hauv txawv teb chaws ntau lug. Txoj kev pulse ntawm laser feem ntau siv infrared laser, nrog rau ze-infrared laser thiab nruab nrab-infrared laser. Cov qhab ntawm laser no muaj cov ntsiab lus pom thiab tsis pom. Thiab qhov rangefinder raws li cov thev naus laus zis no muaj cov kev xav tau qis qis, ceev ceev, kev siv yooj yim qauv, siab peak tso zis zog, siab repetition zaus thiab dav, yog li qhov project no siv txoj kev mem tes los tsim lub handheld laser rangefinder.
