Tamarta Wadnaha ee Er: Gudbiyayaasha Laser-ka galaas

Dhinacyada kala duwanaanshaha laysarka, bartilmaameedka bartilmaameedka, iyo LiDAR, Er: Gudbiyeyaasha laysarka muraayadaha ayaa noqday kuwo si weyn loo isticmaalo infrared-ka dhexe ee leysarka gobolka sababtoo ah badbaadadooda ugu fiican ee indhaha iyo naqshadaynta is haysta. Ka mid ah cabbiraadaha waxqabadkooda, tamarta garaaca wadnaha ayaa door muhiim ah ka ciyaarta go'aaminta awoodda ogaanshaha, baaxadda caymiska, iyo guud ahaan ka jawaab celinta nidaamka. Maqaalkani wuxuu bixiyaa falanqayn qotodheer oo ku saabsan tamarta garaaca wadnaha Er: gudbiyeyaasha leysarka muraayadaha.

1. Waa maxay Tamarta Pulse?

Tamarta garaaca wadnaha waxaa loola jeedaa qadarka tamarta uu sii daayo laysarka ee garaaca wadnaha kasta, sida caadiga ah lagu qiyaaso millijoules (mJ). Waa wax soo saarka awoodda ugu sarreysa iyo muddada garaaca wadnaha: E = P_{ugu sarreysa}×τ. Halkee: E waa tamarta garaaca wadnaha, P_{ugu sarreysa} waa awooda ugu sarreysa,τ waa ballaca garaaca wadnaha.

Sida caadiga ah Er: Laysarka muraayadaha ee ku shaqeeya 1535 nm-dhererka mowjadda fasalka 1-aad ee isha-ammaan-Tamar garaaca garaaca sare waxaa lagu gaari karaa iyadoo la ilaalinayo amniga, taasoo ka dhigaysa inay si gaar ah ugu habboon yihiin codsiyada la qaadi karo iyo dibadda.

2. Qiyaasta Tamarta Wadnaha ee Er:Laasarka muraayadaha

Iyada oo ku xidhan nakhshad, habka bamka, iyo codsiga loogu talagalay, ganacsiga Er: Wariyayaasha laysarka galaasku waxay bixiyaan tamar hal garaac ah oo u dhaxaysa tobanaan microjoules (μJ) ilaa dhowr iyo toban millijoules (mJ).

Guud ahaan, Er: Gudbiyeyaasha muraayadaha leysarka ee loo isticmaalo qaybo kala duwan oo kala duwan ayaa leh tamar garaaca wadnaha ah 0.1 ilaa 1 mJ. Naqshadayaasha bartilmaameedka fog-fog, 5 ilaa 20 mJ ayaa sida caadiga ah loo baahan yahay, halka nidaamyada millatariga ama warshadaha laga yaabo in ay dhaafaan 30 mJ, oo inta badan la isticmaalo laba-ul ama qaab-dhismeedka xoojinta heerarka badan si loo gaaro wax soo saar sare.

Tamarta garaaca wadnaha ee sareysa waxay guud ahaan keentaa in si fiican loo ogaado, gaar ahaan marka lagu jiro xaalado adag sida calaamadaha soo laabashada daciifka ah ama faragelinta deegaanka ee xadka dheer.

3. Waxyaabaha Saameynaya Tamarta Wadnaha

①Waxqabadka Isha Pump

Er: Laysarka muraayadaha waxaa sida caadiga ah bamgareeya diodes laser (LDs) ama flashlamps. LDs waxay bixiyaan hufnaan sare iyo isafgarad laakiin waxay dalbanayaan kuleyl sax ah iyo kantaroolka wareegga wadista.

②Isku-darka Doping iyo Dhererka Usha

Agabka kala duwan ee martida loo yahay sida Er:YSGG ama Er:Yb:Muraayadaha waxay ku kala duwan yihiin heerarkooda doping iyo dhererka korodhka, iyagoo si toos ah u saameeya awoodda kaydinta tamarta.

③Tignoolajiyada Q-Beddelka

Beddelka Q dadban (tusaale, leh Cr: YAG crystals) waxay fududaysaa qaabdhismeedka laakiin waxay bixisaa saxnaanta xakamaynta xaddidan. Beddelka firfircoon ee Q (tusaale, leh unugyada Pockels) waxay siisaa xasillooni sare iyo xakamaynta tamarta.

④Maamulka kulaylka

Marka la eego tamarta garaaca wadnaha sare, kuleylka waxtarka leh ee ka soo baxa ul laysarka iyo qaab dhismeedka qalabka ayaa lagama maarmaan u ah si loo hubiyo xasilloonida wax soo saarka iyo cimri dhererka.

4. Isbarbardhigga Tamarta garaaca wadnaha iyo xaaladaha codsiga

Doorashada saxda ah ee Er: Gudbiyaha laysarka muraayadda waxay si weyn ugu xiran tahay codsiga loogu talagalay. Hoos waxaa ah qaar ka mid ah xaaladaha isticmaalka caadiga ah iyo talooyinka tamarta garaaca wadnaha ee u dhigma:

①Rangefinders Laser-gacanta leh

Astaamaha: is haysta, awood hooseeya, cabbiraadyo-soo noqnoqosho-sare oo gaaban

Tamarta garaaca ee lagu taliyay: 0.5-1 mJ

②UAV Kala-duwanaanta / Ka Hortagga Caqabadda

Sifooyin: kala duwanaansho dhex-ilaa-dheer, jawaab degdeg ah, khafiif ah

Tamarta garaaca ee lagu taliyay: 1-5 mJ

③Nashqadeyaasha Bartilmaameedka Ciidamada

Astaamaha: dhexgalka sare, ka-hortagga faragelinta xooggan, hagida shaqo joojinta muddada-dheer

Tamarta garaaca ee lagu taliyay: 10-30 mJ

④Nidaamyada LiDAR

Astaamaha: heerka soo noqnoqoshada sare, sawirida ama jiilka daruuraha

Tamarta garaaca ee lagu taliyay: 0.1-10 mJ

5. Isbeddellada Mustaqbalka: Tamar Sarreysa & Baakad Kooban

Horumarka socda ee tignoolajiyada doping-ka dhalada ah, qaab dhismeedka bamka, iyo agabka kulaylka, Er: gudbiyeyaasha laysarka muraayadaha ayaa u kobcaya isku darka tamar sare, heerka soo noqnoqda sare, iyo yaraynta. Tusaale ahaan, nidaamyada isku-dhafan kobcinta heerar badan oo leh nashqado firfircoon oo Q ah ayaa hadda keeni kara in ka badan 30 mJ garaaca garaaca iyada oo la ilaalinayo qaab is haysta-ku habboon cabbirka fogaanta iyo codsiyada difaaca ee la isku halleyn karo.

6. Gabagabo

Tamarta garaaca wadnaha waa tilmaame hawleedka muhiimka ah ee qiimaynta iyo doorashada Er:Glass laser transmitters oo ku salaysan shuruudaha codsiga. Sida teknoolajiyada laysarka ay sii wadaan inay horumariyaan, isticmaalayaashu waxay gaari karaan wax soo saar tamar sare leh iyo kala duwanaansho badan oo ka yar, qalab tayo fiican leh. Nidaamyada u baahan waxqabadka muddada dheer, badbaadada indhaha, iyo isku halaynta shaqada, fahamka iyo xulashada qiyaasta tamarta garaaca wadnaha ee habboon ayaa muhiim u ah sare u qaadida hufnaanta iyo qiimaha nidaamka.

Hadii aad'Waxaan raadineynaa wax qabad sare Er:Glass laser transmitters, xor u noqo inaad nala soo xiriirto. Waxaan bixinaa noocyo kala duwan oo noocyo ah oo leh qeexitaan tamarta garaaca wadnaha oo u dhexeysa 0.1 mJ ilaa in ka badan 30 mJ, oo ku habboon codsiyo kala duwan oo kala duwan oo leysarka kala duwan, LiDAR, iyo qoondaynta bartilmaameedka.
