Ukucubungula isignali yinto ebalulekileyo ekumiseleni ukuchaneka kokulinganisa. Ii-algorithms eziphambili zokucubungula isignali, ezifana nokulinganisa isigaba okanye iteknoloji yexesha lokubhabha (TOF), zinokunyusa ukuchaneka kokulinganisa isignali yokubuya. Ukulinganisa isigaba kubala umgama ngokuhlalutya umahluko wesigaba kwisignali yelaser, efanelekileyo kwiimilinganiselo ezichanekileyo; iteknoloji yeTOF ilinganisa ixesha elithathwa yilaser ukuhamba ukusuka kwitransmitter ukuya kwireceiver, efanelekileyo kwiimilinganiselo zomgama omde. Ukongeza, ukwandisa inani lemilinganiselo kunye nokulinganisa iziphumo kunokunciphisa ngempumelelo iimpazamo ezingahleliweyo, ngaloo ndlela kuphucula uzinzo kunye nokuthembeka kweziphumo zokulinganisa. Ngokuphucula amandla okucubungula isignali, ukuchaneka kokulinganisa kwe-laser rangefinders kunokuphuculwa kakhulu.
4. Phucula uYilo lweOptical
Uyilo lwe-optical ludlala indima ebalulekileyo kwiinkqubo zokulinganisa nge-laser. Ukuphucula ukuchaneka kokulinganisa, inkqubo ye-optical kufuneka ibe ne-collimation ephezulu kunye nokuchaneka kokugxila. I-Collimation iqinisekisa ukuba umqadi we-laser uhlala uhambelana xa ukhutshwa, kunciphisa ukusasazeka emoyeni, ngelixa ukuchaneka kokugxila kuqinisekisa ukuba umqadi we-laser ugxininiswe ngokuchanekileyo kumphezulu ekujoliswe kuwo kwaye umqadi wokubuya ungena ngokuchanekileyo kwi-receiver. Ngokulungisa ngokuchanekileyo inkqubo ye-optical, iimpazamo ezibangelwa kukusasazeka kwe-beam kunye nokubonakaliswa zinokuncitshiswa ngempumelelo, ngaloo ndlela kuphuculwe ukuchaneka.
5. Ukunciphisa Impembelelo Kwindalo Esingqongileyo
Izinto ezikwimeko-bume zinokuchaphazela kakhulu ukujikeleza kwelaser. Ngexesha lokulinganisa, uthuli emoyeni, utshintsho lomswakama, kunye ne-gradients yobushushu zinokuphazamisa ukusasazeka kwelaser beam kunye nokwamkelwa kwemiqondiso yokubuya. Ke ngoko, ukugcina imeko-bume yokulinganisa ezinzileyo kubalulekile. Izigqubuthelo zothuli zinokuthintela uthuli ekuphazamiseni umqadi welaser, kwaye iinkqubo zokulawula ubushushu zinokugcina ubushushu obusebenzayo obuzinzileyo kwizixhobo. Ukongeza, ukuphepha ukulinganisa kwiindawo ezinokukhanya okunamandla okanye iindawo ezininzi ezikhanyayo kunokunciphisa impembelelo yokukhanya okungqongileyo kwisignali yelaser. Ngokunciphisa iimpembelelo zokusingqongileyo, ukuchaneka kunye nokuzinza kokujikeleza kwelaser kunokuphuculwa.
