Kev txheeb xyuas ntawm kev txhim kho thiab cov xwm txheej ntawm cov txheej txheem kho qhov muag ua kom zoo dua technology1

Tam sim no nws tsis yooj yim pom tias yuav luag tag nrho cov tub rog cov tub rog lub cev muaj ntau yam khoom siv photoelectric sensor, thiab hauv cov khoom siv hluav taws xob photoelectric no, ntau dua lossis ntau yam ntawm cov kho qhov muag tau siv. Los ntawm cov ntaub ntawv ntawm daim ntawv qhia tshawb fawb los ntawm Tsoomfwv Meskas, peb paub tias txij xyoo 1980 txog 1990, Asmeskas tub rog lub ntsej muag thiab cov duab hluav taws xob thermal thermal yuav tsum muaj 1,147,700 pieces ntawm ntau qhov chaw kho qhov muag, ntawm uas 635,900 pieces ntawm spherical optical parts tsis tau siv. Muaj 234,600 qhov chaw kheej kheej, 181,000 qhov chaw tsim kho qhov muag, thiab 96,200 polyhedral tsom iav tsom iav. Coj M1 tank piv txwv. Nws siv txog 90 lo ntsiab muag, 30 prisms, thiab ntau yam iav, iav qhov rais thiab laser sib xyaw. Lwm qhov piv txwv yog qhov me me AN ​​/ AVS-6 qhov tsav dav hlau hmo ntuj pom kev tsom iav uas siv 9 lub qhov muag pom qhov muag thiab 2 qhov chaw kho qhov muag pom.

Txij li xyoo 1970, cov tub rog siv tshuab kho qhov muag tau sawv cev los ntawm infrared thermal imaging thiab siab-zog lasers tau tsim kho sai. Cov tub rog kho qhov muag pom tsis tau tsuas yog siv cov duab zoo, tab sis kuj tseem me me, lub teeb yuag, thiab cov qauv yooj yim. Qhov no yog kev sim hnyav rau kev lag luam tsim kho qhov muag. Txhawm rau kom tau txais kev txhim kho ntawm lub sijhawm thiab tsim qauv thiab tsim cov khoom lag luam zoo tshaj plaws kho qhov muag, qhov kho qhov muag txheej txheem kev lag luam tau ua tiav cov txheej txheem thev naus laus zis loj loj thiab kev tsim kho tshiab hauv xyoo 1970, thiab tshawb nrhiav thiab tsim ntau yam tshiab ntawm cov khoom kho qhov muag. cov hau kev, xws li thaj chaw aspheric. Kev ua cov txheej txheem ntawm optical seem. Hauv 10 lub xyoo dhau los, cov khoom siv kho qhov muag tshiab kho tshuab tau txuas ntxiv mus thiab nrov npe. Tam sim no, qhov kho qhov muag kho tshuab feem ntau siv txawv teb chaws feem ntau suav nrog:

Khoos phib tawj siv cov kev sib txuas ib qho taw qhia lub pob zeb diamond tig tshuab, kho qhov muag iav lens tshuab, kho qhov muag yas moulding tshuab, khoos phis tawm cov xov tooj sib tsoo thiab polishing tshuab, epoxy resin replication thev naus laus zis, thev naus laus zis tshuab ... thiab tsoos sib tsoo thiab polishing tshuab.

2. Khoos phib tawj hais txog zauv taw tes ib lub pob zeb diamond tig tshuab

Khoos phib tawj hais txog tib lub taw qhia lub pob zeb diamond tig tshuab yog aspheric optical feem ua tshuab uas tau tsim thawj los ntawm Asmeskas Kev Tshawb Fawb Kev Tshawb Fawb Hauv Tebchaws xyoo 1960 thiab tau txhawb thiab siv nyob rau xyoo 1980s. Nws siv cov lus qhia zoo tib yam siv lead ua cov cuab yeej ntawm ultra-precision CNC lathes. Nyob rau hauv kev tswj qhov tseeb ntawm lub tshuab cuab yeej thiab thaj chaw ua haujlwm, nws ncaj qha siv cov cuab yeej pob zeb diamond rau ib qho-taw tes tig mus rau cov txheej txheem aspheric optical qhov chaw uas ua tau raws li cov khoom zoo. Cov thev naus laus zis no siv los ua cov ntawv me me thiab nruab nrab infrared muaju thiab kho qhov muag ntawm cov khoom siv hlau. Nws cov yam ntxwv yog qhov ua tau zoo ntau lawm, kev ua haujlwm siab, ua qhov zoo rov ua dua, tsim nyog rau kev ua kom loj, thiab kev ua cov txheej txheem yog qis dua li kev ua cov khoom lag luam ib txwm muaj. Cov khoom siv kho qhov muag nrog lub taub uas tsawg dua 120mm ua tiav los ntawm lub pob zeb tig lub tshuab no muaj qhov tseeb ntawm 1/2 ～ 1l, thiab lub hauv paus txhais tau hais tias square tus nqi ntawm qhov saum npoo yog 0.02 ～ 0.06mm.

Tam sim no, cov ntaub ntawv uas tuaj yeem ua tiav los ntawm pob zeb diamond tig tshuab yog: non-ferrous hlau, germanium, plastics, infrared optical crystals (mercury cadmium telluride, cadmium antimonide, polysilicon, zinc sulfide, zinc selenide, sodium chloride, potassium chloride, chloride Strontium, magnesium fluoride, calcium fluoride, lithium niobate, KDK siv lead ua) electroless npib tsib xee, beryllium tooj liab, germanium-based chalcogenide iav, thiab lwm yam Cov ntaub ntawv saum toj no tuaj yeem ncaj qha ua raws li qhov ua tau ntawm qhov zoo tshaj plaws kho qhov muag. Cov thev naus laus zis no tseem tuaj yeem ua cov iav, titanium, tungsten thiab lwm yam ntaub ntawv, tab sis tam sim no nws tsis tuaj yeem ua raws li cov tseev kom muaj ntawm qhov chaw kho qhov muag tau zoo thiab yuav tsum muaj kev sib tsoo thiab polishing ntxiv.

Ntxiv rau kev ua ncaj ncaj spherical thiab aspheric kho qhov muag kho qhov muag, khoos phis tawj ntau tswj ib qho taw qhia lub pob zeb diamond tig tshuab kuj tseem siv tau los ua cov txheej txheem ntau yam kho qhov muag tuaj pwm thiab lub ntsej muag kho qhov muag lub cev, xws li ua cov iav moulds, luam ntawv pwm, thiab plastics kho qhov muag. Kev txhaj tshuaj moulding pwm thiab tshuab lub cev rau kev ua thiab rov ua dua ntu epoxy kho qhov muag, thiab lwm yam. ua ke nrog cov pa roj carbon txheej hnyav txheej txheem thiab epoxy resin replication thev naus laus zis, nws tuaj yeem tsim tus nqi pheej yig precision aspheric tsom iav thiab lo ntsiab muag. Yog tias sib tsoo cov khoom siv tau ntxiv rau cov tshuab dhos pob zeb diamond lossis cov cuab yeej siv pob zeb, siv cov khoom siv tau sib dhos, thiab pob zeb diamond txiav yog ua tiav ntawm qhov ntsuas kub ntawm -100 ° C, daim ntawv thov ntau ntawm cov thev naus laus zis yuav raug nthuav dav ntxiv. Tam sim no, Lub Chaw Optical ntawm University of Arizona tau siv cov thev naus laus zis los hloov cov kev siv tshuab kev coj ua, tab sis thaum ua cov iav kho qhov muag, nws tsis tuaj yeem ncaj qha mus rau hauv cov tsom iav kho qhov muag uas ua tau raws li qhov yuav tsum tau ua zoo, thiab hloov kho kom zoo yog tseem yuav tsum tau.

Cov cuab yeej kev lag luam thiab kev cuam tshuam ntawm cov taw tes tib lub pob zeb diamond tig ntawm lub qhov muag pom yog qhov tseeb heev. Piv txwv li, thaum ua tiav 90 ° tawm-axis parabolic iav nrog lub taub ntawm 100 hli, yog cov tsoos sib tsoo thiab polishing txheej txheem siv, qhov tseeb ntawm cov nplaim tuaj yeem ncav cuag 3 hli (5l), thiab lub sijhawm ua tiav 12 Lub Hlis, kev siv nyiaj ntawm txhua daim iav parabolic yog 50,000 Asmeskas las.

Siv cov txheej txheem tig pob zeb diamond, nws tuaj yeem ua tiav hauv 3 lub lis piam, kev ua cov nqi tsuas yog 4 txhiab nyiaj daus las, thiab qhov tseeb ntawm qhov chaw tuaj yeem ncav cuag 0.6μm (1λ). Honeywell ntawm Tebchaws Meskas siv cov thev naus laus zis no los ua cov iav tsom iav ntawm AN / AAD-5 infrared reconnaissance device. Qhov loj ntawm txhua sab ntawm daim iav tig yog 88.9 \ '' 203.2mm, lub tiaj tiaj ntawm txhua sab yog yuav tsum ua kom 1/2, thiab lub kaum sab xis raug yog 90 ° ± 42. Nrog lub tshuab dhos, 124 scanning tsom iav iav tau ua tiav hauv 15 lub hlis, thiab qhov ua tau zoo tau raws li cov qauv tsim kev xav tau. Txhua daim iav tig tau txuag US $ 2,770 piv rau kev ua nrog cov qauv txheej txheem sib xyaw. Honeywell tau siv cov txheej txheem no los tsim 200 lub tsev teev ntuj tig iav, txuag tag nrho ze li ntawm 900,000 Asmeskas las. Ntxiv rau, 100,000 lub tshav dav hlau tsom iav tau ua tiav rau AN / AAD-5 infrared reconnaissance ntaus ntawv, txuag tau ntau dua 10 lab Asmeskas las. Lub sijhawm 10 xyoo txij li 1980 txog 1990, kev ua cov nqi ntawm 4 yam ntawm cov tub rog kho qhov muag, suav nrog dav hlau (50 \'' 50mm), polyhedron (taub 90mm), spherical nto (taub 100 hli), thiab aspherical nto (taub 125 hli), tau raws li kev lag luam txhag cia. Raws li kev txheeb tau cov qhab nia, US Department of Defense tau khaws tag nrho tau txog 400 lab Asmeskas las.
