Koj Puas Paub Txog 1550nm Semiconductor Laser?

1550nm Semiconductor Laser, raws li lub teeb pom kev zoo nrog kev ua tau zoo dua, tau siv dav hauv kev sib txuas lus fiber ntau thaum ntxov li xyoo 1980s, thiab tau siv tom qab siv cov tshuab kho qhov muag fiber ntau. Nws tau maj mam siv hauv Lidar thaum ntxov xyoo pua 21st, suav nrog cua ntsuas Lidar, ntsuas qhov deb ntawm Lidar, Lidar rau kev tiv thaiv tsheb, thiab Lidar rau kev tsav tsheb tsis siv neeg.

Radar, raws li ib tug tseem ceeb txhais tau tias ntawm lub tsheb obstacle kev zam, tau tam sim no tsim los ntawm tsuas yog ultrasonic radar mus rau theem ntawm complementary coexistence ntawm ultrasonic radar, millimeter-yoj radar thiab lidar. Lidar, nrog nws cov kev daws teeb meem siab kom zoo, ushered nyob rau hauv lub sij hawm ntawm kev loj hlob sai. Tsis siv neeg tsav tsheb tshuab tau dhau los ua cov qauv dav dav, thiab lub tsheb-mounted lidar tau ntsib kev loj hlob tawg nyob rau xyoo tas los no.

Tam sim no, lub teeb qhov chaw ntawm lub tsheb-mounted lidar yog tib yam li lub lidar nyob rau hauv lub sweeper. Lawv feem ntau siv 905 nm lasers, uas muaj teeb meem kev nyab xeeb ntawm tib neeg qhov muag. Tshwj xeeb tshaj yog thaum kev ua hauj lwm deb mus txog ntau tshaj 150 m thiab lub optical zog ntawm 905 nm laser tshaj qhov pib ntawm tib neeg qhov muag kev nyab xeeb, lasers nyob rau hauv tib neeg lub qhov muag kev nyab xeeb band yuav tsum tau siv. Piv nrog 905 nm lasers, 1550 nm lasers nrog tib lub zog yog 100, 000 lub sij hawm zoo dua rau tib neeg lub qhov muag. Feem ntau, nyob rau hauv tib qhov chaw loj thiab mem tes dav, qhov siab tshaj plaws tso cai raug thiab qhov siab tshaj plaws qhov siab tshaj plaws qhov muag pom lub zog ntawm 1550 nm laser yog ntau qhov kev txiav txim siab ntau dua li ntawm 905 nm laser.

Piv nrog rau 905nm, qhov zoo ntawm 1550nm laser yog tias 1550nm laser muaj zog atmospheric penetration muaj peev xwm thiab siab dua nrhiav kom raug, thiab yuav ua rau kom qhov deb deb ntawm 250 meters los yog txawm 300 meters. Lub 1550nm wavelength laser muaj zog tiv thaiv kev cuam tshuam, kev sib tsoo zoo dua, thiab qhov ci ci siab ntawm lub teeb ci. Cov txiaj ntsig no kuj ua rau lub emission thiab txais tos ntawm lub laser ntau dua, thiab tuaj yeem ua tiav cov khoom zoo dua. Nyob rau tib lub sijhawm, 1550nm wavelength laser muaj qhov sib txawv tsis muaj zog thiab qhov chaw me me, thiab qhov chaw txoj kab uas hla tsuas yog ib feem peb ntawm 905nm ntawm qhov deb ntawm 100 meters.

Lub 1550nm laser muaj lub wavelength ntev, ua rau qis qis thiab nqus tau, ua rau nws yog qhov kev xaiv tsim nyog rau kev sib kis ntev dua fiber ntau. Tsis tas li ntawd, nws tsis tshua muaj kev cuam tshuam los ntawm huab cua turbulence thiab huab cua, ua rau nws txhim khu kev qha thiab ua haujlwm zoo hauv kev siv sab nraum zoov.

Piv nrog rau lwm cov lasers, 1550nm lasers muaj zog ntau dua thiab siv zog tsawg, yog li txo cov nqi khiav lag luam. Qhov no ua rau nws zoo tagnrho rau kev lag luam thiab kev siv kho mob.

Lwm qhov zoo dua ntawm 1550nm laser yog nws lub peev xwm nkag mus rau cov ntaub so ntswg rau kev kho mob xws li kev phais thiab kev kho mob. Nws kuj yog siv nyob rau hauv ophthalmology los kho cov kab mob xws li glaucoma thiab ntshav qab zib retinopathy.

Tsis tas li ntawd, 1550nm lasers yog siv rau hauv kev siv tub rog xws li laser ntau yam thiab lub hom phiaj tsim vim tsis pom kev. Nws kuj tseem siv rau hauv cov khoom siv hluav taws xob xws li DVD players thiab cov ntaub ntawv kho qhov muag.

Zuag qhia tag nrho, 1550nm lasers muaj ntau qhov zoo dua lwm cov lasers hais txog kev ua tau zoo, kev ntseeg tau, thiab ntau yam. Nws cov yam ntxwv tshwj xeeb ua rau nws yog ib qho cuab yeej tseem ceeb hauv ntau qhov chaw thiab tseem muaj kev cuam tshuam loj rau kev siv tshuab thiab kev tsim kho tshiab.
