Kev Tshawb Fawb Zaus ntawm Er: Iav Laser Transmitters

Hauv cov tshuab kho qhov muag xws li laser ranging, LiDAR, thiab target recognition, Er:Glass laser transmitters siv dav hauv kev siv tub rog thiab pej xeem vim lawv qhov muag muaj kev nyab xeeb thiab kev ntseeg siab. Ntxiv rau lub zog pulse, repetition rate (zaus) yog qhov tseem ceeb rau kev ntsuam xyuas kev ua tau zoo. Nws cuam tshuam rau lub laser's teb ceev, cov ntaub ntawv tau txais ceev, thiab muaj feem cuam tshuam nrog kev tswj hwm thermal, kev tsim hluav taws xob, thiab kev ruaj khov ntawm lub kaw lus.

1. Lub Zaus ntawm Laser yog dab tsi?

Lub zaus ntawm laser yog hais txog tus naj npawb ntawm cov pulses uas tso tawm ib chav ntawm lub sijhawm, feem ntau ntsuas hauv hertz (Hz) lossis kilohertz (kHz). Kuj tseem hu ua tus nqi rov ua dua, nws yog qhov qhia tau zoo tseem ceeb rau cov lasers pulsed.
Piv txwv li: 1 Hz = 1 lub laser pulse ib ob, 10 kHz = 10,000 laser pulses ib ob. Feem ntau Er:Glass lasers ua haujlwm hauv hom pulsed, thiab lawv cov zaus yog txuas nrog cov zis waveform, system sampling, thiab lub hom phiaj echo processing.

2. Qhov Zaus Ntau Zaus ntawm Er:Iav Lasers

Nyob ntawm seb lub laser'Raws li kev tsim qauv thiab cov kev cai ntawm daim ntawv thov, Er: Iav laser transmitters tuaj yeem ua haujlwm los ntawm hom ib zaug xwb (qis li 1 Hz) mus txog kaum tawm kilohertz (kHz). Cov zaus siab dua txhawb kev luam theej sai, kev taug qab tas mus li, thiab kev tau txais cov ntaub ntawv tuab, tab sis lawv kuj ua rau muaj kev xav tau ntau dua rau kev siv hluav taws xob, kev tswj hwm thermal, thiab lub neej laser.

3. Cov Yam Tseem Ceeb Uas Cuam Tshuam Rau Qhov Rov Ua Dua

①Qhov Chaw Twj Tso Kua Mis thiab Kev Tsim Khoom Siv Hluav Taws Xob

Cov chaw twj tso kua mis laser diode (LD) yuav tsum txhawb nqa kev hloov kho ceev ceev thiab muab lub zog ruaj khov. Cov modules fais fab yuav tsum teb tau zoo thiab ua haujlwm tau zoo los tswj cov voj voog qhib / kaw ntau zaus.

②Kev Tswj Xyuas Kub

Qhov zaus siab dua, qhov cua sov ntau dua yuav tsim tawm ib lub sijhawm. Cov dej kub zoo, TEC tswj qhov kub, lossis cov qauv txias microchannel pab tswj cov zis ruaj khov thiab txuas ntxiv lub neej ua haujlwm ntawm lub cuab yeej.

③Txoj Kev Hloov Q

Kev hloov pauv Q-passive (piv txwv li, siv Cr: YAG crystals) feem ntau yog qhov tsim nyog rau cov lasers tsawg zaus, thaum kev hloov pauv Q-active (piv txwv li, nrog cov acousto-optic lossis electro-optic modulators xws li Pockels cells) ua rau muaj kev ua haujlwm ntau zaus nrog kev tswj hwm programmable.

④Tsim Qauv

Cov qauv tsim laser me me, txuag hluav taws xob ua kom lub zog pulse tseem nyob ruaj khov txawm tias nyob rau ntawm cov zaus siab.

4. Cov Lus Qhia Txog Kev Sib Piv Zaus thiab Daim Ntawv Thov

Cov xwm txheej siv sib txawv xav tau cov zaus ua haujlwm sib txawv. Kev xaiv qhov rov ua dua yog qhov tseem ceeb rau kev ua kom muaj kev ua tau zoo tshaj plaws. Hauv qab no yog qee qhov kev siv thiab cov lus pom zoo:

①Zaus Qis, Hom Zog Siab (1–20 Hz)

Zoo tagnrho rau kev tua laser ntev thiab kev xaiv lub hom phiaj, qhov twg kev nkag mus thiab kev ruaj khov ntawm lub zog yog qhov tseem ceeb.

②Zaus Nruab Nrab, Hom Zog Nruab Nrab (50–500 Hz)

Haum rau kev lag luam ranging, navigation, thiab cov systems nrog cov zaus nruab nrab xav tau.

③Zaus Siab, Hom Zog Tsawg (> 1 kHz)

Zoo tshaj plaws rau LiDAR systems uas cuam tshuam nrog array scanning, point cloud generation, thiab 3D modeling.

5. Cov Qauv Txuj Ci

Raws li kev koom ua ke laser txuas ntxiv mus, tiam tom ntej ntawm Er: Glass laser transmitters tab tom hloov zuj zus hauv cov lus qhia hauv qab no:

①Ua ke cov nqi rov ua dua siab dua nrog cov zis ruaj khov
②Kev tsav tsheb ntse thiab kev tswj hwm zaus dynamic
③Kev tsim qauv sib dua thiab siv hluav taws xob tsawg
④Cov qauv tswj ob qho tib si rau ob qho tib si zaus thiab lub zog, ua kom muaj kev hloov pauv hom yooj yim (piv txwv li, kev luam theej duab / kev tsom mus rau / kev taug qab)

6. Xaus Lus

Qhov zaus ua haujlwm yog qhov tseem ceeb hauv kev tsim thiab xaiv Er:Glass laser transmitters. Nws tsis yog tsuas yog txiav txim siab qhov ua tau zoo ntawm kev tau txais cov ntaub ntawv thiab kev tawm tswv yim ntawm lub kaw lus xwb tab sis kuj cuam tshuam ncaj qha rau kev tswj hwm thermal thiab lub neej laser. Rau cov neeg tsim khoom, nkag siab txog qhov sib npaug ntawm zaus thiab lub zog—thiab xaiv cov kev txwv uas haum rau daim ntawv thov tshwj xeeb—yog qhov tseem ceeb rau kev ua kom zoo dua ntawm lub system.
