Iimveliso

I-1064nm Wavelength Nanosecond Pulse Fiber Laser sisixhobo esenziwe ngobuchule obuchanekileyo esifanelekileyo kwiinkqubo zeLiDAR kunye nezicelo ze-OTDR. Inamandla alawulayo ukusuka kwi-0 ukuya kwi-100 watts, iqinisekisa ukulungelelaniswa kwiimeko ezahlukeneyo zokusebenza. Izinga lokuphindaphinda elihlengahlengiswayo lelaser liphucula ukufaneleka kwayo ekufumaneni i-LIDAR ngexesha lokubhabha, ikhuthaza ukuchaneka nokusebenza kakuhle kwimisebenzi ekhethekileyo. Ukongeza, ukusetyenziswa kwayo kwamandla aphantsi kugxininisa ukuzinikela kwemveliso ekusebenzeni okungabizi kakhulu nokuqaphela okusingqongileyo. Olu dibaniso lolawulo lwamandla oluchanekileyo, izinga lokuphindaphinda eliguquguqukayo, kunye nokusebenza kakuhle kwamandla kwenza ukuba ibe yimpahla exabisekileyo kwiindawo zobungcali ezifuna ukusebenza okuphezulu kwe-optical.

LIi-aser diodes, ezidla ngokufinyezwa njenge-LD, zibonakaliswa ngokusebenza kakuhle, ubungakanani obuncinci kunye nobomi obude. Ekubeni i-LD inokuvelisa ukukhanya okuneempawu ezifanayo ezifana nobude be-wavelength kunye nesigaba, ukuhambelana okuphezulu lolona phawu lubalulekileyo. Iiparameter eziphambili zobugcisa: ubude be-wavelength, i-lth, i-operating current, i-operating voltage, amandla okukhupha ukukhanya, i-divergence angle, njl.

Ii-laser rangefinders zisebenza ngemigaqo emibini ephambili: indlela ye-direct time-of-flight kunye nendlela ye-phase shift. Indlela ye-direct time-of-flight ibandakanya ukukhupha i-laser pulse ukuya kwindawo ekujoliswe kuyo kunye nokulinganisa ixesha elithathayo ukuze ukukhanya okubonakalayo kubuye. Le ndlela ilula inika imilinganiselo echanekileyo yomgama, kunye nesisombululo sendawo esiphenjelelwa zizinto ezifana nobude be-pulse kunye nesantya se-detector.

Kwelinye icala, indlela yokutshintsha isigaba isebenzisa i-high-frequency sinusoidal intensity modulation, inika indlela yokulinganisa eyahlukileyo. Nangona izisa ukungaqondakali kokulinganisa, le ndlela ithandwa kakhulu kwi-handheld rangefinders kumgama ophakathi.

Ezi rangefinders zinezinto eziphambili, kuquka izixhobo zokujonga ukukhulisa okuguquguqukayo kunye nokukwazi ukulinganisa isantya esihambelanayo. Ezinye iimodeli zide zenze ukubalwa kwendawo kunye nomthamo kwaye zenze lula ukugcinwa kunye nokudluliselwa kwedatha, nto leyo ephucula ubuchule bazo bokusebenza.

1. Imodyuli yoKubona: Kubandakanya umthombo wokukhanya onemigca enye kunye nowemigca emininzi, kunye neenkqubo zelaser zokukhanyisa. Isebenzisa umbono womatshini wokwenza izinto ngokuzenzekelayo efektri, ilinganisa umbono womntu kwimisebenzi efana nokuqaphela, ukufumanisa, ukulinganisa, kunye nesikhokelo.


2. Inkqubo: Izisombululo ezipheleleyo ezibonelela ngemisebenzi eyahlukeneyo yokusetyenziswa kwimizi-mveliso, ezigqwesileyo ekusebenzeni kakuhle nasekusebenziseni iindleko ngaphezu kokuhlolwa ngabantu, zibonelela ngedatha enokulinganiswa yemisebenzi equka ukuchonga, ukufumanisa, ukulinganisa, kunye nesikhokelo.
