Sezvo hondo ichiwedzera asymmetric, vanhuwo zvavo nevamwe vasiri varwi vanova chikamu chikuru chevanhu vanofa, pamwe chete nekukuvara kwepfuma kusingatarisirwe.Mauto, hongu, anotarisira kunzvenga marudzi aya ekukuvadzwa nekuparadzwa.Nekufambisira mberi matekinoroji anogonesa kunyatsojeka kubva kuzvombo zvavo, ivo vanodawo zvirinani kunongedza uye kugona kunanga, vachiramba vakahwanda.Yakavandudzwa tekinoroji yekunangisa iyo inobvumira kucherechedzwa uye kuzivikanwa kune yakarebesa nhambwe kubva kune vanogadzira inodiwa zvakare.Semuenzaniso, ma lasers akanakisa pakunongedza, asi zvakakosha kuti vamwe vakwanise kuvharidzira mufananidzo wacho zvakare.
Kugadzirisa matambudziko aya ekunangisa, mauto akaisa ma lasers anovabvumira kuti vasangotaridza chinangwa panofanirwa kurova zvombo, asi kuti vashandise aya ma lasers kuyera chinhambwe chechinangwa, kuvhenekera nzvimbo yakatenderedza, kana kunongedzera kune vamwe chinhu. zvekufarira.Kuona painongedzerwa nema lasers, kuronda nhanho dzinofamba, uye kuderedza kukuvadzwa kwechibvumirano kunoda masisitimu ekufungidzira anoona ma lasers anoshanda mumunda.Room-temperature indium gallium arsenide (InGaAs) makamera anopa vashandisi kugona uku masikati kana husiku.
Mazhinji laser-anotungamirwa munitions anotungamirwa nema lasers ane wavelength ye1.06 μm.Aya lasers ane simba kwazvo uye anogona kushandiswa kunongedza kune zvinhu mamaira akawanda kure.Nhambwe yacho inoganhurirwa zvikurukuru nokuti mushandisi anogona kuona zvakarurama zvaari kuronga.Izvi zvinosanganisira laser nzvimbo, chinangwa, uye zvinhu zvakatenderedza chinangwa.Parizvino, masisitimu mazhinji anoshandisa indium antimonide (InSb) detector array kuratidza nzvimbo yacho.Aya maInSb masisitimu akatetepa kuti abvumire mhinduro pasi kune 1.0 μm laser wavelength, iri pasi peyakajairwa InSb peak senitivity range (pakati pe3 ne5 μm).Iro renji rinoshandiswa pakushandisa kwayo kukuru sepakati-wave IR thermal detector.
InSb makamera anobvumira iyo infrared laser kuti ionekwe uye inopa ruzivo rwemamiriro akatenderedza laser nzvimbo nekuda kwekupisa kwekubuda kwechiitiko.Iyo yakaderera yeaya masisitimu ndeyekuti detector inoda kutonhora kwakakosha (kudzika kusvika 77K) uye kunzwa kwavo kune 1.06-μm lasers kwakashata, nekuda kwe70% uye kamuri-tembiricha kushanda.Ivo vanogonesa yekufungidzira laser mavara pane yakakura standoff chinhambwe ine yakareruka system.
MUFANANIDZO1
MaLaser haango shandiswa kutungamira mauto kune avo vavanoda, asi zvakare anogona kupa murwi ruzivo nezvechinangwa nenzvimbo dzayo.Laser range inowana inobvumira mushandisi kuona kureba kune chinangwa.Aya lasers ikozvino anoshandisa inosvika 1.5-μm wavelength.Iyi wavelength inoonekwa se "yakachengeteka-ziso"nekuti simba harina kutarisisa retina yeziso, uye simba rekuona rinodiwa kupofumadza mumwe munhu akarohwa nelaser rakakwira zvakanyanya.Aya ma lasers haaonekwe kune manheru ekuona goggles (NVGs) pamwe neziso, nekudaro achiaita akavanda zvakakodzera.Chakanakira ndechekuti chinangwa hachizive kuti vari kucherechedzwa nelaser;chakashata ndechekuti murwi wehondo anewo dambudziko rekuziva kana akananga pachinangwa.Nekuti InGaAs zvakare inotarisisa kune-akachengeteka maziso lasers, iyo SWIR yekufungidzira InGaAs makamera ari kuiswa kuitira kuti varwi vehondo vaone kuti yavo yekunongedza ichiri kubhoikana nemazvo, kunyangwe iyo system yakavharirwa mumunda.
Laser inonyanyozivikanwa panhandare yehondo ndiyo yakasungirirwa papfuti yemurwi, uye inowanzoshandisa wavelength yakatenderedza 850 nm.Iyi laser pointer inoshandiswa nemasoja kunongedza zvibodzwa kune mumwe nemumwe, pamwe nekubatsira mukunangisa pfuti dzavo husiku kana vakapfeka maNVG.Ma lasers aya haaonekwe nevanhu, asi anoonekwa kumagirazi.Iwo pfuti lasers haana ziso-akachengeteka uye anoonekwa uchishandisa akawanda mamwe marudzi e detector matekinoroji, ekare uye matsva.Dambudziko hombe nderekuti nepo murwi achida iwo akanakisa maNVGs kuti aone mberi uye panguva dzakasvibira pakati pehusiku, muvengi anogona kuona zviri nyore ma lasers nekare uye isingadhure yehusiku yekuona goggle tekinoroji.InGaAs mapikicha ane mukana wakasiyana wekuve ese ari maviri kumashure-anoenderana, sezvavanofungidzira ekare lasers anoshandiswa neNVGs, uye ivo vanokwanisa kufananidzira "yakachengeteka-ziso" uye inotevera-chizvarwa laser masisitimu.
Imwe SWIR kamera yakagadziridzwa yakanangana neUS Army's Soldier Mobility uye Rifle Targeting System, SUI's KTX Camera inoratidzira yakanyanya kunzwa mu900 kusvika 1700 nm wavelength renji uye inogona kushandiswa mumhando dzakasiyana-yepasi-chiedza-level yekufungidzira mabasa, kusanganisira laser. kuonekwa.Iine yakafara dhizaini yekufungidzira mune chikamu chenyeredzi kuvhenekera kwezuva, iyo SWIR mufananidzo wakanakira kuvharidzira kuongororwa uye inogona kubatanidzwa zviri nyore mumaUAV, mota dzepasi dzisina munhu, kana zvimwe zvigadziriso zvemarobhoti kana zvakabatwa nemaoko uko ukuru nehuremu hwakakosha.
Mune inotevera-chizvarwa imaging masisitimu, ma lasers haangotarise chinhambwe chechinangwa, kureva laser range finders, asi anozotendera mifananidzo yakareba-refu kuburikidza nemhute inovhara, mhute, uye huruva.LADAR uye renji-gated imaging inoshandisa laser kuvhenekera chinangwa kureba.Ichi chinhambwe chakareba chekumira chinobvumira murwi kuti aone zvibodzwa pakureba pasi pemamiriro echiedza uye kunyangwe nemhute nehutsi.
Mazhinji masisitimu ari pasi pekuvandudzwa ari kushandisa 1.5-μm lasers nekuda kwezvikonzero zvekuchengetedza maziso uye nekuti zvakare akavharika kune yazvino NVG tekinoroji, iyo yakawedzera mumaoko evavengi.Mazhinji eaya anotevera-anotevera masisitimu ari kuvandudzwa nekamuri-tembiricha InGaAs arrays kuchengetedza huremu, simba, uye saizi pane system.Izvi zviitiko zvinosanganiswa neakanyanya-sensitivity maficha eInGaAs-SWIR ma detectors, achipa yakagadziridzwa mashandiro ane akachengeteka mamiriro ekupedzisira mushandisi uye vasina mhosva vakamira.
