Lilense tsa zoom tsa Long-Wave Infrared (LWIR)e se e le lisebelisoa tsa bohlokoa haholo litsamaisong tsa sejoale-joale tsa indasteri le tsa tšireletso. Bokhoni ba tsona bo ikhethang ba ho hapa tlhahisoleseling ea mocheso maemong a fapaneng bo li etsa hore li be ntle bakeng sa lits'ebetso tse hlokang ho nepahala, ho tšepahala le ho ikamahanya le maemo. Sehloohong sena, re hlahloba bokhoni, lits'ebetso le melemo ea lilense tsa zoom tsa LWIR maemong a indasteri le a tšireletso.
1. Tshebetso ea Lilense tsa LWIR Zoom
Lilense tsa zoom tsa LWIR li sebetsa ka har'a sebaka sa spectral sa 8-14 μm, e leng se li nolofalletsang ho lemoha le ho bona matšoao a mocheso a sa bonahaleng mahlong. Bokhoni bona bo finyelloa ka tšebeliso ea lisebelisoa tse khethehileng tse kang likhalase tsa Germanium, Zinc Selenide, le Chalcogenide, tse nang le phetiso e phahameng sebakeng sa LWIR. Lisebelisoa tsena li koahetsoe ka hloko ka mekhahlelo e thibelang ho bonahatsa ho eketsa ts'ebetso le ho fokotsa tahlehelo ea lets'oao.
Tshebetso ya zoom e nolofatswa ke dikopano tse nepahetseng tsa optical le mekgwa e nang le enjene e fetolang bolelele ba focus ka tsela e fetohang. Ditokiso tsena di dumella basebetsi ho tsepamisa maikutlo dikarolong tse itseng tsa sebaka ntle le ho lahlehelwa ke temoho ya maemo. Moralo wa optical hangata o kenyelletsa dikarolo tse kang aspherical ho fokotsa diphetoho le ho netefatsa boleng bo hodimo ba setshwantsho ho pholletsa le sebaka sa zoom. Boenjiniere bo tswetseng pele bo netefatsa motsamao o boreleli le o nepahetseng, hangata o laolwa ke di-stepper motors kapa di-actuator tsa piezoelectric bakeng sa ho nepahala ho ntlafetseng.
2. Litšobotsi tsa Bohlokoa tsa Lense tsa Zoom tsa LWIR
2.1 Phetoho ea Bolelele ba Focal e Fetotsoeng
Bokhoni ba ho fetola bolelele ba focal nakong ea ts'ebetso bo nolofalletsa lilense tsa zoom tsa LWIR ho atamela libaka tsa bohlokoa tse khahlisang. Sena se bohlokoa haholo bakeng sa ho khetholla lintho kapa lintho tse sa tloaelehang libakeng tse fapaneng. Bolelele ba focal hangata bo tloha ho limilimithara tse 'maloa ho isa ho limilimithara tse makholo a' maloa, e leng se fanang ka tšireletso ea sebaka se seholo le kholo e phahameng.
2.2 Bokhoni bo Ntlafalitsoeng ba ho Hlokomela
Ka ho fana ka taolo e nepahetseng ea zoom, lilense tsa LWIR li ntlafatsa katleho ea litsamaiso tsa ho lekola. Sena se finyelloa ka ho kopanngoa ha li-detector tse nang le qeto e phahameng, joalo ka li-microbolometer tse sa pholisoang kapa li-detector tsa photon tse pholileng, tse fanang ka litšoantšo tse qaqileng tsa mocheso. Motsoako oa li-zoom optics le li-detector tse sebetsang hantle o netefatsa hore phapang ea mocheso o fokolang le o monyane e nkuoa ka nepo.
2.3 Tšireletso e Sephara ea Kantle
Lilense tsena li loketse haholo-holo bakeng sa libaka tse pharaletseng tsa kantle, li fana ka tšireletso bakeng sa libaka tse kholo ha li ntse li boloka bokhoni ba ho tsepamisa maikutlo lintlheng tse itseng ha ho hlokahala. Tšimo ea pono (FOV) ke paramethara ea bohlokoa, e nang le meralo e ntlafalitsoeng ho leka-lekanya tlhokomelo ea sebaka se seholo le bokhoni ba ho atametsa bakeng sa tlhahlobo e qaqileng.
2.4 Tshebetso e Matla Maemong a Phephetsang
Lilense tsa zoom tsa LWIR li etselitsoe ho sebetsa ka mokhoa o tšepahalang maemong a leholimo a thata, ho kenyeletsoa le moholi, pula le maemo a khanya e tlase. Bokhoni ba tsona ba ho nka litšoantšo tsa mocheso ha bo angoe ke mabone a tikoloho, e leng se etsang hore li be ntle bakeng sa tlhokomelo ea 24/7. Ho feta moo, liphahlo tse tsoetseng pele tsa lense le matlo a koetsoeng li sireletsa khahlanong le mabaka a tikoloho a kang lerōle, mongobo le ho feto-fetoha ha mocheso.
3. Likopo Mafapheng a Liindasteri le a Tšireletso
3.1 Litsela tse Kholo le Lipalangoang
Lilense tsa zoom tsa LWIR li bohlokoa haholo ho lekoleng phallo ea sephethephethe le ho lemoha lintho tse sa tloaelehang litseleng tse kholo, litereneng le marokhong. Hangata litsamaiso tsena li hloka lilense tse nang le libaka tse telele tsa ho lemoha—ho fihlela lik'hilomithara tse 'maloa—le kutlo e phahameng ea mocheso ho khetholla mathata a kang ho chesa lienjene kapa phihlello e sa lumelloang. Bokhoni ba ho fetola zoom ka mokhoa o feto-fetohang bo netefatsa hore basebetsi ba ka tsepamisa maikutlo kapele libakeng tse khahlisang ntle le ho lahleheloa ke temoho ea maemo ka kakaretso.
3.2 Tlhokomelo ea Lebōpo le Meeli
Tšireletsong ea likepe le ea meeli, lilense tsa zoom tsa LWIR li fana ka temoho ea likepe, likoloi le batho ka bomong libakeng tse telele. Bokhoni ba tsona ba ho hapa matšoao a mocheso bo netefatsa katleho.tlhokomelo, esita le bosiu kapa maemong a sa bonahaleng hantle. Ditshebediso tse tlwaelehileng di kenyeletsa ho lemoha dithaba tse sa dumellwang, ho beha leihlo metsamao ya dikepe, le ho hlwaya ditshoso tse ka bang teng dibakeng tse thibetsweng. Dilense tsena hangata di kopantswe le radar le di-sensor tse ding bakeng sa temoho e felletseng ya maemo.
3.3 Polokeho le Tlhahlobo ea Liindasteri
Liindasteri li sebelisa lilense tsa zoom tsa LWIR bakeng sa tlhahlobo ea mocheso oa meralo ea motheo ea bohlokoa, joalo ka liphaephe, li-grid tsa motlakase le lisebelisoa tsa tlhahiso. Lilense tsena li thusa ho lemoha ho chesa haholo, ho lutla, kapa likotsi tse ling tse ka bang teng pele li eketseha. Mohlala, lits'ebetsong tsa motlakase, ho nka litšoantšo tsa mocheso ho ka khetholla libaka tse chesang tse bakoang ke likhokahano tse hlephileng kapa lipotoloho tse imetsoeng haholo, ho thibela nako e jang nako ea ho sebetsa le likotsi.
3.4 Tšireletso ea Metseng le ea Litoropo
Lilense tsa zoom tsa LWIR li bapala karolo ea bohlokoa ho sireletseng libaka tsa litoropo le ho sireletsa meeli ea libaka tse bonolo. Bokhoni ba tsona ba ho beha leihlo libaka tse kholo le ho atamela liketsahalo tse itseng bo li etsa hore li be bohlokoa haholo ho thibeleng phihlello e sa lumelloang kapa ho khetholla litšokelo. Ho kopanngoa le bohlale ba maiketsetso (AI) le tlhahlobo ea video ho ntlafatsa katleho ea tsona ka ho nolofalletsa ho lemoha le ho latela litšokelo ka boiketsetso.
4. Bokamoso ba Lilense tsa LWIR Zoom
Ha makala a tshireletso le a indasteri a ntse a tswela pele ho fetoha, tlhoko ya mahlale a tswetseng pele a ho nka ditshwantsho jwalo ka dilense tsa zoom tsa LWIR e lebelletswe ho hola. Dintlafatso moralong wa dilense, jwalo ka tshebediso ya dielemente tsa optical tse hasanyang le di-detector tse ntlafetseng tsa mocheso, di tla ntlafatsa qeto, sebaka le tshebediso. Ho feta moo, kopanyo ya AI le di-algorithms tsa ho ithuta ka mochini e tla nolofalletsa tlhahlobo e bohlale ya ditshwantsho le ho etsa diqeto ka boiketsetso, ho tiisa dilense tsa zoom tsa LWIR e le lejwe la motheo la ditsamaiso tsa sejwalejwale tsa tlhokomelo.
5. Qetello
Lilense tsa zoom tsa LWIRli fetola tsela eo liindasteri le mekhatlo ea tšireletso li atamelang tlhokomelo le tlhokomelo ka eona. Ka bokhoni ba tsona ba ho ikamahanya le maemo a fapaneng, ho fana ka litšoantšo tse ntle haholo, le ho netefatsa ts'ebetso e tšepahalang, lilense tsena ke letsete la bohlokoa bakeng sa mokhatlo ofe kapa ofe o batlang ho ntlafatsa bokhoni ba oona ba ts'ebetso. Ebang ke bakeng sa ho netefatsa polokeho ea sechaba, ho sireletsa meeli, kapa ho boloka meralo ea motheo, lilense tsa zoom tsa LWIR li fana ka mekhoa e fapaneng le bokhoni bo sa bapisoang.
