Kwangowe-1916, isazinzulu esidumileyo samaJuda uEinstein safumanisa imfihlo yeeleser. I-Laser (igama elipheleleyo: iLight Amplification by Stimulated Emission of Radiation), elithetha "ukwandiswa yimitha yokukhanya evuselelweyo", idunyiswa njengenye into enkulu eyenziwe luluntu ukususela kwinkulungwane yama-20, ilandela amandla enyukliya, iikhompyutha, kunye nee-semiconductors. "Yimela ekhawulezayo", "umlawuli ochanekileyo", kunye "nokukhanya okukhanyayo". Igama elipheleleyo lesiNgesi le-laser sele lichaza ngokupheleleyo inkqubo ephambili yokwenza i-laser. I-Laser inoluhlu olubanzi lwezicelo, ezinje ngokumakishwa kwe-laser, ukuwelda kwe-laser, ukusika kwe-laser, unxibelelwano lwe-fiber optic, ukujikelezisa kwe-laser, i-LiDAR, njalo njalo. Namhlanje siza kuthetha ngendlela ii-laser ezifikelela ngayo umsebenzi wokulinganisa umgama.
Umgaqo wokwahlulahlula nge-laser
Ngokubanzi, kukho iindlela ezimbini zokulinganisa umgama kusetyenziswa iilaser: indlela yepulse kunye nendlela yesigaba. Umgaqo we-laser pulse ranging kukuba ilaser ekhutshwa sisixhobo sokukhupha ilaser ibonakaliswe yinto elinganisiweyo ize ifunyanwe yi-receiver ngaxeshanye. Ngokurekhoda ngexesha lohambo oluya nokubuya lwelaser, isiqingatha semveliso yesantya sokukhanya kunye nexesha lohambo oluya nokubuya ngumgama ophakathi kwesixhobo sokujikeleza kunye nento elinganisiweyo. Ukuchaneka kwendlela yepulse yokulinganisa umgama ngokubanzi kumalunga ne-+/- iisentimitha ezili-10. Indlela yesigaba ayilinganisi isigaba selaser, kodwa ilinganisa isigaba sesignali esilungisiweyo kwilaser.
Indlela yokusika i-laser
Emva kokuqonda umgaqo wokwahlulahlula nge-laser, makhe sijonge indlela esebenza ngayo i-laser ranking. Ngokwesiqhelo, ukwahlulwahlula nge-laser echanekileyo kufuna ukusetyenziswa kwe-total reflection prism, ngelixa i-rangefinder esetyenziselwa ukulinganisa indlu inokulinganisa ngokuthe ngqo ukurhawuzelelwa ukusuka kumphezulu wodonga olugudileyo. Oku kungenxa yokuba umgama usondelelene, kwaye amandla esignali abonakaliswa ngasemva kukukhanya anamandla ngokwaneleyo. Nangona kunjalo, ukuba umgama ukude kakhulu, i-engile yokukhupha i-laser kufuneka ilingane nesibuko sokubonakalisa iyonke, kungenjalo isignali yokubuya iya kuba buthathaka kakhulu ukufumana umgama ochanekileyo. Nangona kunjalo, kubunjineli obusebenzayo, ukwahlulwahlulwa nge-laser yabasebenzi kuya kusebenzisa amaphepha eplastiki amancinci njengeendawo ezikhanyayo ukusombulula ingxaki yokubonakaliswa okunzulu kwe-laser diffuse. Umatshini wokurhangqa nge-laser esemgangathweni ophezulu unokufikelela kumlinganiselo ochanekileyo ukuya kuthi ga kwi-1 millimeter, okwenza ii-laser zifaneleke kwiinjongo ezahlukeneyo zokulinganisa ngokuchanekileyo.
Njengeshishini eliphambili elidibanisa uphando nophuhliso kunye nemveliso, iLumisopot iphuhlise ngokuzimeleyo iimodyuli ze-905nm 1200m semiconductor laser ranging, iimodyuli ze-1535nm 3-15km erbium glass laser ranging, kunye nezinye iimodyuli zokulinganisa i-laser distance long. Ngokungafaniyo nezinye iimveliso ze-laser ranging zezinye iinkampani, iimveliso zethu zibonisa ngokupheleleyo iimpawu zobukhulu obuncinci, ubunzima obulula, ukusebenza kakuhle kweendleko, kunye nokukwazi ukuhambisa ngobuninzi. Ngaphezu koko, iimodeli zethu zemveliso zahlukile ngakumbi kwaye zinokuhlangabezana nazo zonke iimfuno ze-laser ranging. Ukuba unomdla kwiimveliso zethu, nceda uzive ukhululekile ukunxibelelana nathi.
