I-algorithms yokucubungula umqondiso ophezulu, njengomlinganiselo wesigaba okanye iteknoloji yexesha lokuhamba (TOF), inokunyusa ukuchaneka kwemilinganiselo yesignali yokubuya. Umlinganiselo wesigaba ubala umgama ngokuhlalutya ukungafani kwesigaba kwisignali ye-laser, efanelekileyo kwimilinganiselo ephezulu yokuchaneka; Itekhnoloji ye-TOF ilinganisa ixesha elithathiweyo ukuze i-laser ihambe isuka kwi-transmitter iye kumamkeli, ilungele imilinganiselo yomgama omde. Ukongezelela, ukwandisa inani lemilinganiselo kunye nokulinganisa iziphumo kunokunciphisa ngokufanelekileyo iimpazamo ezizenzekelayo, ngaloo ndlela kuphuculwe ukuzinza nokuthembeka kweziphumo zokulinganisa. Ngokuphucula amandla okusebenza komqondiso, ukuchaneka komlinganiselo we-laser rangefinders kunokuphuculwa kakhulu.

4. Phucula i-Optical Design

Uyilo lwe-Optical ludlala indima ebalulekileyo kwiinkqubo zoluhlu lwelaser. Ukuphucula ukuchaneka kokulinganisa, inkqubo ye-optical kufuneka ibe nokudibanisa okuphezulu kunye nokugxila ngokuchanekileyo. I-Collimation iqinisekisa ukuba i-laser beam ihlala ihambelana xa ikhutshwa, ukunciphisa ukusasazeka emoyeni, ngelixa ukugxila ngokuchanekileyo kuqinisekisa ukuba i-laser beam igxininiswe ngokuchanekileyo kwindawo ekujoliswe kuyo kwaye i-beam yokubuyisela ingena ngokuchanekileyo kumamkeli. Ngokulinganisa ngokuchanekileyo inkqubo ye-optical, iimpazamo ngenxa yokuchithwa kwe-beam kunye nokucamngca kunokunciphisa ngokufanelekileyo, ngaloo ndlela kuphuculwe ukuchaneka.

5. Nciphisa iMpembelelo yokuSingqongileyo

Imiba yokusingqongileyo inokuchaphazela kakhulu ukuvela kwelaser. Ngexesha lokulinganisa, uthuli olusemoyeni, utshintsho lokufuma, kunye nemithamo yobushushu inokuphazamisana nokusasazwa komqadi welaser kunye nokwamkelwa kwemiqondiso yokubuya. Ngoko ke, ukugcinwa kwendawo yokulinganisa okuzinzileyo kubalulekile. Izigqubuthelo zothuli zinokuthintela uthuli ekuphazamiseni umqadi we-laser, kunye neenkqubo zokulawula ubushushu zinokugcina ubushushu obuzinzileyo besixhobo.
