Ha thekenoloji ea laser e ntse e ata haholo mafapheng a kang a ho qala, puisano, ho tsamaea, le ho utloa u le hole, mekhoa ea ho feto-fetoha le khouto ea mats'oao a laser le eona e se e fapane ebile e rarahane. E le ho ntlafatsa bokhoni ba ho thibela ho kena-kenana le ho kena-kenana, ho nepahala ho fapaneng, le katleho ea phetisetso ea data, baenjiniere ba thehile mekhoa e fapaneng ea khouto, ho kenyeletsa Precision Repetition Frequency (PRF) Code, Variable Pulse Interval Code, le Pulse Code Modulation (PCM).
Sengoliloeng sena se fana ka tlhahlobo e tebileng ea mefuta ena e tloaelehileng ea khouto ea laser ho u thusa ho utloisisa melaoana ea eona ea ts'ebetso, likarolo tsa tekheniki, le maemo a ts'ebeliso.
1. Khoutu ea Pheta-pheta e nepahetseng (PRF Code)
①Theknoloji Molao-motheo
Khoutu ea PRF ke mokhoa oa ho khouta o fetisang mats'oao a sekhahla ka lebelo le tsitsitseng la ho pheta-pheta (mohlala, 10 kHz, 20 kHz). Litsamaisong tsa laser rangeing, pulse e 'ngoe le e' ngoe e khutlisitsoeng e khetholloa ho ipapisitsoe le maqhubu a eona a hlakileng a tlhahiso, a laoloang ka thata ke sistimi.
②Likarolo tsa Bohlokoa
Sebopeho se bonolo le litšenyehelo tse tlase tsa ts'ebetsong
E loketse litekanyo tsa nako e khuts'oane le lipehelo tse bonts'ang haholo
Ho bonolo ho hokahanya le litsamaiso tsa lioache tsa elektroniki tsa setso
E sa sebetseng hantle libakeng tse rarahaneng kapa maemong a sepheo se fapaneng ka lebaka la kotsi ea“echo ea boleng bo bongata”tšitiso
③Maemo a Kopo
Lisebelisoa tsa Laser rangefinders, lisebelisoa tsa ho lekanya sebaka se le seng, lisebelisoa tsa tlhahlobo ea indasteri
2. Khoutu ea Nako ea Nako ea Pulse e feto-fetohang (Khoutu e sa fetoheng kapa e feto-fetohang ea Pulse Interval Code)
①Theknoloji Molao-motheo
Mokhoa ona oa khouto o laola linako tse lipakeng tsa maqhubu a laser hore e be a sa tsitsang kapa a pseudo-random (mohlala, ho sebelisa jenereithara ea tatelano ea pseudo-random), ho fapana le ho ts'oaroa. Boemo bona bo sa reroang bo thusa ho khetholla matšoao a ho khutla le ho fokotsa tšitiso ea litsela tse ngata.
②Likarolo tsa Bohlokoa
Bokhoni bo matla ba ho thibela tšitiso, bo loketseng bakeng sa ho lemoha sepheo libakeng tse rarahaneng
E hatella li-echoes tsa ghost ka katleho
Ho rarahana ha li-decoding tse phahameng, tse hlokang li-processor tse matla haholoanyane
E loketse bakeng sa ho fumana mefuta e mengata e nepahetseng haholo le ho fumana lipheo tse ngata
③Maemo a Kopo
Sistimi ea LiDAR, litsamaiso tsa ho lekola li-UAV / ts'ireletso, litsamaiso tsa laser tsa sesole le lits'ebetso tsa boitsebahatso ba sepheo
3. Pulse Code Modulation (PCM Code)
①Theknoloji Molao-motheo
PCM ke mokhoa oa ho feto-fetoha ha dijithale moo matshwao a analoge a nkuwang, a hlahiswa, mme a kenngwe ka mokgwa wa binary. Litsamaisong tsa puisano tsa laser, data ea PCM e ka tsamaisoa ka laser pulses ho fihlela phetiso ea tlhahisoleseling.
②Likarolo tsa Bohlokoa
Phetiso e tsitsitseng le khanyetso e matla ea lerata
E khona ho fetisa mefuta e fapaneng ea tlhahisoleseling, ho kenyeletsoa molumo, litaelo le data ea boemo
E hloka kamahanyo ea oache ho netefatsa hore ho na le li-decoud tse nepahetseng ho moamoheli
E hloka li-modulator tse sebetsang hantle haholo le li-demodulator
③Maemo a Kopo
Litsi tsa puisano tsa Laser (mohlala, Free Space Optical communication system), taolo ea remoutu ea laser bakeng sa limisaele/sefofane, ho khutlisa data ho sistimi ea laser telemetry.
4. Qetello
Joalo ka“boko”ea lisebelisoa tsa laser, theknoloji ea khouto ea laser e etsa qeto ea hore na tlhahisoleseling e fetisoa joang le hore na sistimi e sebetsa hantle hakae. Ho tloha ho likhoutu tsa mantlha tsa PRF ho isa ho modulation e tsoetseng pele ea PCM, khetho le moralo oa maano a khouto e fetohile senotlolo sa ho ntlafatsa ts'ebetso ea sistimi ea laser.
Ho khetha mokhoa o nepahetseng oa khouto ho hloka ho nahanoa ka botlalo mabapi le boemo ba ts'ebeliso, maemo a tšitiso, palo ea lipehelo, le tšebeliso ea matla a sistimi. Ka mohlala, haeba sepheo e le ho haha sistimi ea LiDAR bakeng sa mohlala oa 3D oa litoropong, ho khethoa khoutu e fapaneng ea nako ea phallo e nang le bokhoni bo matla ba anti-jamming. Bakeng sa lisebelisoa tse bonolo tsa ho metha sebaka, khoutu e nepahetseng ea ho pheta-pheta e ka ba e lekaneng.
