1) Intshayelelo kwi-Infrared Optics
I-Infrared Optics isetyenziselwa ukuqokelela, ukugxila okanye ukudibanisa ukukhanya kuluhlu lwe-wavelength phakathi kwe-760 kunye ne-14,000 nm. Le nxalenye yemitha ye-IR yohlulwe kwakhona ibe ziindidi ezine ezahlukeneyo zokujonga:
| Kufuphi noluhlu lwe-Infrared (NIR) | 700 - 900 nm |
| Uluhlu lwe-infrared yamaza amafutshane (SWIR) | 900 - 2300 nm |
| Uluhlu lwe-Infrared oluphakathi (MWIR) | 3000 - 5000 nm |
| Uluhlu olude lwe-Infrared (LWIR) | 8000 - 14000 nm |
2) I-Infrared yamaza amafutshane (SWIR)
Izicelo ze-SWIR zigubungela uluhlu olusuka kwi-900 ukuya kwi-2300 nm. Ngokungafaniyo nokukhanya kwe-MWIR kunye ne-LWIR ekhutshwa kwinto ngokwayo, i-SWIR ifana nokukhanya okubonakalayo ngengqiqo yokuba iifotoni zibonakaliswa okanye zifunxwe yinto, ngaloo ndlela ibonelela ngokungafaniyo okufunekayo kwi-imaging ephezulu. Imithombo yokukhanya kwendalo efana nokukhanya kokuqalisa kunye nokuqaqamba kwangasemva (aka nightglow) zezo zikhuphayo ze-SWIR kwaye zibonelela ngokukhanya okugqwesileyo kumfanekiso wangaphandle ebusuku.
Inani lezicelo eziyingxaki okanye ezingenzekiyo kusetyenziswa ukukhanya okubonakalayo ziyenzeka kusetyenziswa iSWIR. Xa usenza umfanekiso kwi-SWIR, umphunga wamanzi, umsi womlilo, inkungu, kunye nezinto ezithile ezifana nesilicon ziyabonakala. Ukongeza, imibala ebonakala iphantse yafana kwinto ebonakalayo inokwahlulwa ngokulula kusetyenziswa iSWIR.
I-SWIR imaging isetyenziselwa iinjongo ezininzi ezifana nebhodi ye-elektroniki kunye nokuhlolwa kweeseli zelanga, ukuhlola ukuvelisa, ukuchonga kunye nokuhlelwa, ukucupha, ukuchasa ukwenza umgunyathi, inkqubo yokulawula umgangatho kunye nokunye.
3) I-Infrared yeMid-Wave (MWIR)
Iinkqubo ze-MWIR zisebenza kwi-3 ukuya kwi-5 micron uluhlu. Xa uthatha isigqibo phakathi kweenkqubo ze-MWIR kunye ne-LWIR, umntu kufuneka athathele ingqalelo izinto ezininzi. Okokuqala, imimandla ye-atmospheric yendawo efana nokufuma kunye nenkungu kufuneka ithathelwe ingqalelo. Iinkqubo ze-MWIR azichatshazelwa kancinci kukufuma kuneenkqubo ze-LWIR, ngoko ke ziphezulu kwizicelo ezifana nokucupha unxweme, uphononongo lwezothutho kwiinqanawa okanye ukukhuselwa kwezibuko.
I-MWIR inosulelo olukhulu lwe-atmospheric kune-LWIR kwiimozulu ezininzi. Ke ngoko, i-MWIR ikhethwa ngokubanzi kwizicelo zokucupha kuluhlu olude oludlula umgama we-10 km ukusuka kwinto.
Ngapha koko, i-MWIR ikwayindlela engcono ukuba ufuna ukubona izinto ezinobushushu obuphezulu njengezithuthi, iinqwelomoya okanye imijukujelwa. Kulo mfanekiso ungezantsi umntu unokubona ukuba iiplamu zokukhupha ezishushu zibonakala kakhulu kwi-MWIR kune-LWIR.
4) I-Long-Wave Infrared (LWIR)
Iinkqubo ze-LWIR zisebenza kwi-8 ukuya kwi-14 micron uluhlu. Zikhethwa kwizicelo kunye nezinto ezikufutshane zobushushu begumbi. Iikhamera ze-LWIR azichatshazelwa kangako lilanga kwaye ngoko zingcono ekusebenzeni kwangaphandle. Ngokuqhelekileyo ziinkqubo ezingapholiswanga ezisebenzisa ii-microbolometers ze-Focal Plane Array, nangona iikhamera ze-LWIR ezipholileyo zikhona kwaye zisebenzisa izixhobo zokubona iMercury Cadmium Tellurium (MCT). Ngokwahlukileyo koko, uninzi lweekhamera ze-MWIR zifuna ukupholisa, zisebenzisa initrogen engamanzi okanye iStirling cycle cooler.
Iinkqubo ze-LWIR zifumana inani elibanzi lezicelo ezifana nokuhlolwa kwesakhiwo kunye neziseko zophuhliso, ukufumanisa isiphene, ukufumanisa igesi kunye nokunye. Iikhamera ze-LWIR zidlale indima ebalulekileyo ngexesha lobhubhani we-COVID-19 njengoko zivumela umlinganiselo okhawulezayo nochanekileyo wobushushu bomzimba.
5) Isikhokelo sokuKhetha i-IR Substrates
Izinto ze-IR zineempawu ezahlukileyo ezivumela ukuba ziqhube kakuhle kwi-spectrum ye-infrared. I-IR Fused Silica, i-Germanium, i-Silicon, i-Sapphire, kunye ne-Zinc Sulfide / i-Selenide, nganye inamandla okusetyenziswa kwe-infrared.
IZinc Selenide (ZnSe)
I-Zinc selenide yinto ekhaphukhaphu-tyheli, ikhompawundi eyomeleleyo equka i-zinc kunye neselenium. Idalwe ngokudityaniswa komphunga weZinc kunye negesi ye-H2 Se, eyenza njengamaphepha kwi-graphite substrate. Iyaziwa ngomlinganiselo wayo ophantsi wokufunxa kwaye ovumela ukusetyenziswa okugqwesileyo kwee-CO2 lasers.

IJamani (Ge)
I-Germanium inomsi obumnyama obumnyama obomvu kunye nesalathiso se-refractive ye-4.024 kunye ne-low optical dispersion. Inobunzima obukhulu kunye noBulukhuni be-Knoop (kg / mm2): 780.00 evumela ukuba iqhube kakuhle kwi-optics yentsimi kwiimeko ezinqabileyo.
| Eyona Range yoThutho | Izicelo ezifanelekileyo |
| 2 - 16μm | I-LWIR - i-MWIR imaging ye-Thermal (xa i-AR igqunywe), iimeko ezinqabileyo zamehlo |
Isilicon (S)
I-silicon inenkangeleko eluhlaza okwesibhakabhaka kunye nomthamo ophezulu we-thermal eyenza ilungele izibuko ze-laser kunye ne-silicon wafers kushishino lwe-semiconductor. Inesalathiso se-refractive se-3.42. Amacandelo e-silicon asetyenziswa kwizixhobo zombane kungenxa yokuba imisinga yayo yombane inokudlula kwiikhondakhthi zesilicon ngokukhawuleza kakhulu xa kuthelekiswa nabanye abaqhubi, ingaphantsi kweGe okanye iZnSe. I-AR yokwambathisa iyacetyiswa kwizicelo ezininzi.

IZinc Sulfidi (ZnS)
I-Zinc Sulfide lukhetho oluhle kakhulu lwe-infrared sensors luhambisa kakuhle kwi-IR kunye ne-spectrum ebonakalayo. Ngokuqhelekileyo lukhetho olunendleko ngaphezu kwezinye izixhobo ze-IR.
| Eyona Range yoThutho | Izicelo ezifanelekileyo |
| 0.6 - 18μm | I-LWIR - i-MWIR, ebonakalayo kunye nephakathi-amaza okanye amaza emide e-infrared sensors |
Ukukhetha kwakho i-substrate kunye ne-anti-reflection coating iya kuxhomekeka ekubeni yeyiphi i-wavelength efuna ukuhanjiswa okuphambili kwisicelo sakho. Umzekelo, ukuba uhambisa ukukhanya kwe-IR kuluhlu lwe-MWIR, i-germanium inokuba lukhetho oluhle. Ukusetyenziswa kwe-NIR, isafire inokuba yinto efanelekileyo.
Ezinye iinkcukacha onokufuna ukuziqwalasela kukhetho lwakho lwe-infrared optics lubandakanya iipropathi ze-thermal kunye nesalathiso se-refraction. Iimpawu ze-thermal ze-substrate zilinganisa indlela esabela ngayo kubushushu. Rhoqo, izinto ze-infrared optical ziya kuboniswa kumaqondo obushushu ahlukeneyo. Ezinye izicelo ze-IR zivelisa ubushushu obukhulu. Ukuqinisekisa ukuba i-IR substrate ifanelekile kwisicelo sakho uya kufuna ukujonga isalathisi somgangatho kunye nomlinganiso wokwandiswa kwe-thermal (CTE). Ukuba i-substrate enikeziweyo inesalathisi esiphezulu se-gradient, inokuba nentsebenzo ye-optical esezantsi xa isetyenziswe kwi-thermally volatile setting. Ukuba ine-CTE ephezulu, inokwandisa okanye inkontileka kwizinga eliphezulu linikwe utshintsho olukhulu kwiqondo lokushisa. Izixhobo ezisetyenziswa rhoqo kwi-infrared optics ziyahluka ngokubanzi kwisalathiso se-refraction. Ngokomzekelo, iGermaninium inesalathiso sokuphindaphinda kwe-4.0003, xa kuthelekiswa ne-1.413 ye-MgF. Ukufumaneka kwee-substrates ezinoluhlu olubanzi lwesalathiso sokuphindaphinda kunika ukuguquguquka okongeziweyo kuyilo lwenkqubo. Ukusasazwa kwezinto ze-IR kulinganisa utshintsho kwisalathiso se-wavelength ngokubhekiselele kwi-wavelength kunye ne-chromatic aberration, okanye ukwahlukana kwe-wavelength. Ukusasazwa kubalwa ngokwenani, ngokuphambeneyo, kunye nenombolo ye-Abbe, echazwa njengomlinganiselo wesalathiso se-refractive kwi-d wavelength minus 1, ngaphezu komahluko phakathi kwesalathiso sokuphindaphinda kumgca we-f kunye no-c. Ukuba i-substrate inenani le-Abbe elikhulu kune-55, i-dispersive encinci kwaye siyibiza ngokuba yimpahla yesithsaba. Ii-substrates ezininzi ezisasazwayo ezinamanani e-Abbe angaphantsi kwama-55 abizwa ngokuba yi-flint materials.
