Tamarta garaaca ee laysarka

Tamarta garaaca ee laysarka waxaa loola jeedaa tamarta uu gudbiyo garaaca laysarka halbeeg kasta oo waqti ah. Caadiyan, laysarka waxay soo saari karaan hirar joogto ah (CW) ama hirar garaac ah, iyadoo kan dambe uu si gaar ah muhiim ugu yahay codsiyo badan sida habaynta agabka, dareemaha fog, qalabka caafimaadka, iyo cilmi-baarista sayniska. Fahmidda astaamaha tamarta garaaca laysarka ayaa muhiim u ah hagaajinta waxqabadkeeda iyo hagaajinta hufnaanta codsiga.

1. Qeexidda iyo Cabbiraadda Tamarta Garaaca

Tamarta garaaca laysarka waa tamarta ay sii deyso garaaca laysarka kasta, oo badanaa lagu cabbiro joules (J). Si ka duwan laysarka hirarka joogtada ah (CW), laysarka garaaca leh waxay sii deeyaan tamar waqti gaaban gudaheed, baaxadda tamartuna waxay caadi ahaan la xiriirtaa muddada garaaca (ballaca garaaca) iyo awoodda ugu sarreysa.

Tamarta garaaca wadnaha waxaa lagu xisaabin karaa qaacidada soo socota: E = Ppeak × τ. Halka E uu yahay tamarta garaaca wadnaha (joules), Ppeak waa awoodda ugu sarreysa ee garaaca wadnaha (watts), iyo τ waa muddada garaaca wadnaha (ilbiriqsiyo). Taas macnaheedu waa tamarta garaaca wadnaha waxay si toos ah ula xiriirtaa awoodda ugu sarreysa iyo ballaca garaaca wadnaha.

2. Arrimaha Saameeya Tamarta Garaaca

Dhowr arrimood ayaa saameeya tamarta garaaca ee laysarka, oo ay ku jiraan:

①Naqshadeynta iyo Nooca laysarka:
Noocyada kala duwan ee laysarka ayaa saameeya cabbirka tamarta garaaca wadnaha. Tusaale ahaan, laysarka adag ee xaaladda adag badanaa waxay bixiyaan tamar garaac oo sare, oo ku habboon codsiyada u baahan wax soo saar koronto oo sare. laysarka fiilooyinka, dhanka kale, waxay soo saari karaan garaacyo leh awood sare iyagoo hagaajinaya hirarkooda.

②Muddada Garaaca (Ballaca Garaaca):
Ballaca garaaca oo gaaban, ayaa awoodda ugu sarreysa sii kordheysa wakhti go'an, taasoo u oggolaanaysa tamar garaac oo sare. Ballaca garaaca ee laysarka garaaca ayaa caadi ahaan la hagaajin karaa inta u dhaxaysa nanoseconds iyo picoseconds, iyadoo garaaca gaaban si weyn loogu isticmaalo codsiyada saxnaanta sare leh sababtoo ah awooddooda ugu sarreysa.

③Waxtarka Beddelka Tamarta iyo Awoodda Laser-ka:
Waxtarka laysarka ayaa si toos ah u go'aamiya wax soo saarka tamarta. Nidaamyada laysarka qaarkood waxay kor u qaadi karaan hufnaanta beddelka iyagoo hagaajinaya naqshadeynta qalabka faa'iidada ama godka laysarka, taasoo kordhinaysa tamarta garaaca wadnaha.

④Qalab-sameeyayaasha laysarka:
Nidaamyo badan oo laysar ah oo awood sare leh, cod-weyneeyayaasha ayaa loo isticmaalaa in lagu kordhiyo tamarta wax soo saarka. Iyada oo loo marayo kor u qaadis marxalado badan leh, tamarta garaaca si weyn ayaa loo kordhin karaa.

⑤Hadda Laydhka Darawalka:
Hawada wadista ee nidaamka diode-ka laysarka ama laysarka waa arrin muhiim ah oo saameynaysa awooddeeda wax soo saarka iyo tamarta garaaca. Marka la hagaajiyo hadda, xaaladda kicinta laysarka waa la beddeli karaa, taasoo saameynaysa wax soo saarka tamarta garaaca.

3. Adeegsiga Tamarta Lugta Laysarka

Cabbirka tamarta garaaca laysarka ayaa go'aamisa ku habboonaanshaheeda meelaha kala duwan. Qaar ka mid ah codsiyada caadiga ah waxaa ka mid ah:

①Habaynta Qalabka:
Alxanka laysarka, jarista, iyo xaraashka, tamarta garaaca wadnaha si sax ah ayaa loo xakameyn karaa si loo gaaro habayn hufan oo sax ah. Tamar garaac oo sareysa ayaa ku habboon habaynta agabka birta, halka garaaca tamarta yar loo isticmaalo daawaynta dusha sare ee wanaagsan.

②Codsiyada Caafimaadka:
Laser-ka garaaca wadnaha ayaa si weyn loogu isticmaalaa caafimaadka, gaar ahaan qalliinnada laysarka, daawaynta maqaarka, iyo daawaynta indhaha. Tusaale ahaan, laser-ka garaaca wadnaha oo leh tamar sare ayaa diiradda saari kara tamarta laysarka ee hirar gaar ah meelaha yaryar si loo tirtiro unugyada buka ama loo daweeyo xaaladaha indhaha.

③LiDAR iyo Dareemidda Fog:
Tiknoolajiyadda LiDAR waxay ku tiirsan tahay laysarka tamarta garaaca sare si loo helo kala-duwanaansho sax ah iyo sawir-qaadis. La socodka deegaanka, wadista iskeed u shaqeysa, iyo la socodka diyaaradaha aan duuliyaha lahayn, cabbirka tamarta garaaca ayaa si toos ah u saameeya masaafada ogaanshaha iyo xallinta nidaamka LiDAR.

④Cilmi-baaris Saynis:
Liisaradaha garaaca wadnaha ayaa sidoo kale door muhiim ah ka ciyaara tijaabooyinka fiisigiska, kiimikada, iyo bayoolajiga. Iyagoo si sax ah u xakameynaya tamarta garaaca wadnaha, saynisyahannadu waxay sameyn karaan spectroscopy-ga saxda ah ee laser-ka, dardargelinta walxaha, iyo cilmi-baarista qaboojinta laser-ka.

4. Hababka lagu Kordhiyo Tamarta Garaaca

Hababka caadiga ah ee lagu kordhiyo tamarta garaaca laysarka waxaa ka mid ah:

①Ka faa'iidayso hagaajinta dhexdhexaadka ah:
Iyada oo la dooranayo hab faa'iido oo ku habboon oo loo hagaajiyo naqshadeynta godka laysarka, tamarta wax soo saarka ee laysarka waa la kordhin karaa.

②Ballaarinta Laser-ka ee marxalado badan leh:
Qalab-sameeyayaasha marxaladaha badan leh ayaa si tartiib tartiib ah u kordhin kara tamarta garaaca ee laysarka si ay u buuxiyaan shuruudaha codsiyada kala duwan.

③Kordhinta Hadda ama Ballaca Garaaca Wadista:
Hagaajinta qulqulka darawalka ama ballaca garaaca laysarka waxay keeni kartaa tamar garaac oo weyn.

④Tiknoolajiyada Cadaadiska Garaaca:
Iyada oo la adeegsanayo farsamooyinka cadaadiska garaaca wadnaha, muddada garaaca wadnaha waa la gaabin karaa, taasoo kordhinaysa awooddeeda ugu sarreysa isla markaana sii deynaysa tamar badan waqti gaaban gudaheed.

5. Gunaanad

Tamarta garaaca laysarka waa halbeeg muhiim ah oo si toos ah u saameeya waxqabadka iyo isticmaalka laysarka dhinacyo kala duwan. Iyadoo la horumarinayo tignoolajiyada laysarka, laysarka garaaca leh waxay yeelan doonaan codsiyo ballaaran oo warshado badan ah. Laga bilaabo mashiinka saxda ah ilaa dareenka fog iyo daaweynta caafimaadka, wax soo saarka tamarta sare ee laysarka garaaca leh wuxuu furaa fursado cusub. Fahmidda fikradaha aasaasiga ah ee tamarta garaaca wadnaha iyo arrimaha saameynta leh waxay gacan ka geysan kartaa sameynta doorashooyin cilmiyeed oo badan marka la naqshadeynayo oo la adeegsanayo nidaamyada laysarka.
