Cov lus piav qhia luv luv ntawm lub laser range finder
Laser rangefinders tau siv dav hauv kev tshawb fawb saum toj kawg nkaus, kev soj ntsuam kev sib ntaus sib tua, tso tsheb hlau luam, dav hlau, nkoj thiab phom loj laser rangefinders los ntsuas qhov deb ntawm lub hom phiaj, thiab ntsuas qhov siab ntawm huab, dav hlau, cuaj luaj thiab cov satellites. Nws yog ib qho tseem ceeb ntawm cov cuab yeej cuab tam los txhim kho qhov tseeb ntawm siab tanks, aircraft, nkoj thiab artillery. Vim qhov txo qis ntawm cov nqi ntawm laser ntau yam finders, laser range finders tau maj mam pib siv hauv kev lag luam, uas tuaj yeem siv dav hauv kev ntsuas thiab tswj, mines, chaw nres nkoj thiab lwm yam kev lag luam.
Laser ceeb toom kev nyab xeeb thiab ceev faj rau kev siv Lasers yog cov khoom siv hluav taws xob siv hluav taws xob ntau. Cov lasers muaj hwj chim loj tuaj yeem siv los txiav thiab vuam cov ntaub ntawv hlau, yog li lasers muaj kev puas tsuaj loj rau tib neeg lub cev, tshwj xeeb tshaj yog tib neeg lub qhov muag, thiab yuav tsum tau saib xyuas tshwj xeeb thaum siv lawv.
Thoob ntiaj teb, muaj kev sib koom ua ke thiab sib koom ua ke kev ceeb toom kev nyab xeeb rau lasers. Lasers muab faib ua plaub pawg (Class1 ~ Class4). Class I lasers muaj kev nyab xeeb rau tib neeg, Class II lasers ua rau me me rau tib neeg, thiab Class III thiab siab dua lasers muaj kev nyab xeeb rau tib neeg. Lasers tuaj yeem ua rau muaj kev puas tsuaj loj rau tib neeg, yog li yuav tsum tau them nyiaj tshwj xeeb thaum siv lawv kom tsis txhob raug rau tib neeg lub qhov muag.
Nyob rau hauv thaum ntxov 1990s, ntau lub tuam txhab loj hauv Tebchaws Europe thiab Tebchaws Meskas tau ua tiav cov khoom lag luam muaj semiconductor laser diodes, uas tau hloov pauv cov txiaj ntsig ntawm kev siv lasers. Rau lwm hom lasers, vim lub complex mechanism ntawm laser tiam, lub ntim, hnyav tshwj xeeb tshaj yog loj, thiab lub hwj chim noj yog heev, uas zoo heev txwv tsis pub siv cov lasers. Qhov tshwm sim ntawm semiconductor lasers tau daws cov teeb meem no. Nrog rau kev loj hlob ntxiv ntawm semiconductor laser technology, tus nqi maj mam txo, thiab nws daim ntawv thov ntim thiab daim ntawv thov teb txuas ntxiv mus, thiab nws daim ntawv thov kev cia siab yog qhov zoo. Semiconductor lasers yog me me, lub teeb nyob rau hauv hnyav, siab nyob rau hauv kev ntseeg siab, siab nyob rau hauv conversion efficiency, tsis tshua muaj zog noj, yooj yim nyob rau hauv tsav lub hwj chim, muaj peev xwm ntawm kev ncaj qha modulation, yooj yim nyob rau hauv cov qauv, tsis tshua muaj nqi, muaj kev nyab xeeb siv, thiab muaj ntau yam kev siv. Xws li kev cia khoom kho qhov muag, laser luam ntawv, laser phototypesetting, laser ntau yam, barcode scanning, muaj kev tshawb nrhiav, kuaj thiab ntsuas ntsuas, laser zaub, khoom siv kho mob, tub rog, kev ruaj ntseg, kev tshawb nrhiav teb, kev tsim kho qib thiab cim ntsuas ntsuas, kuaj thiab qhia kev qhia, theem teeb pom kev zoo thiab laser qhia, qib laser thiab ntau yam cim qhov chaw, thiab lwm yam. Qee qhov tshwj xeeb zoo ntawm semiconductor lasers ua rau lawv zoo heev rau kev siv tub rog, xws li kev sib tw, aiming ntawm phom, tua simulation systems, dig muag, kev taw qhia rau submarine kev sib txuas lus, fuzes, kev ruaj ntseg, thiab lwm yam. Txij li thaum nws tuaj yeem tsav tau los ntawm cov roj teeb zoo tib yam, qee qhov kev teeb tsa cov cuab yeej cuab tam tuaj yeem ua tau.
Lub wavelength bands ntawm semiconductor lasers uas tau tsim thiab muab tso rau hauv kev ua lag luam yog 370nm, 390nm, 405nm, 430nm, 480nm, 635nm, 650nm, 670nm, 780nm, 808nm, 501nm, 801nm. m, lwm 1310nm thiab 1550nm feem ntau yog siv rau kev sib txuas lus kho qhov muag fiber ntau. 405nm - 670nm yog lub teeb pom kev, 780nm - 1550nm yog lub teeb ci infrared, thiab 390nm - 370nm yog lub teeb ultraviolet. Cov khoom siv thev naus laus zis thiab cov thev naus laus zis thev naus laus zis ua tus qauv ntawm kev ntsuas kev deb ntawm kev lag luam.
