Ukuqaliswa kweteknoloji yokuvavanya i-photoelectric
Itekhnoloji yokufumanisa ifoto yombane yenye yetekhnoloji ephambili yetekhnoloji yolwazi lombane, ebandakanya ikakhulu itekhnoloji yokuguqula ifoto yombane, ukufunyanwa kolwazi olubonakalayo kunye netekhnoloji yokulinganisa ulwazi kunye netekhnoloji yokucwangcisa ifoto yombane wolwazi lomlinganiselo. Njengendlela ye-photoelectric ukufezekisa ukulinganisa okuhlukeneyo komzimba, ukukhanya okuphantsi, ukulinganisa ukukhanya okuphantsi, ukulinganisa kwe-infrared, ukuskena ukukhanya, ukulinganisa ukukhanya, ukulinganisa i-laser, ukulinganisa i-fiber optical, ukulinganisa umfanekiso.
Itekhnoloji yokufumanisa i-Photoelectric idibanisa itekhnoloji ye-optical kunye netekhnoloji ye-elektroniki ukulinganisa ubungakanani obahlukeneyo, obunezi mpawu zilandelayo:
1. Ukuchaneka okuphezulu. Ukuchaneka komlinganiselo we-photoelectric yeyona iphezulu phakathi kwazo zonke iintlobo zeendlela zokulinganisa. Ngokomzekelo, ukuchaneka kokulinganisa ubude kunye ne-laser interferometry inokufikelela kwi-0.05μm / m; Umlinganiselo we-Angle nge-grating moire fringe indlela inokufezekiswa. Isisombululo sokulinganisa umgama phakathi komhlaba kunye nenyanga nge-laser rangeing method inokufikelela kwi-1m.
2. Isantya esiphezulu. Umlinganiselo we-Photoelectric uthatha ukukhanya njengophakathi, kwaye ukukhanya sesona santya sisasaza ngokukhawuleza phakathi kwazo zonke iintlobo zezinto, kwaye ngokungathandabuzekiyo sesona sikhawulezayo sokufumana nokuhambisa ulwazi ngeendlela zokukhanya.
3. Umgama omde, uluhlu olukhulu. Ukukhanya yeyona ndlela ilungileyo yolawulo olukude kunye ne-telemetry, njengesikhokelo sezixhobo, ukulandelela ifoto yombane, i-telemetry kamabonwakude njalo njalo.
4. Umlinganiselo ongaqhagamshelwanga. Ukukhanya kwinto elinganisiweyo kunokubonwa njengento engekho amandla okulinganisa, ngoko akukho ngxabano, ukulinganisa okuguquguqukayo kunokufezekiswa, kwaye iyona ndlela isebenzayo kwiindlela ezahlukeneyo zokulinganisa.
5. Ubomi obude. Kwithiyori, amaza okukhanya akaze agqitywe, nje ukuba ukuveliswa kwakhona kwenziwa kakuhle, kunokusetyenziswa ngonaphakade.
6. Ngobuchule bokwenza ulwazi oluluqilima kunye nekhompuyutha, ulwazi oluntsonkothileyo lunokusingathwa ngaxeshanye. Indlela ye-photoelectric nayo ilula ukulawula nokugcina ulwazi, kulula ukuyiqonda i-automation, kulula ukudibanisa nekhompyutheni, kwaye kulula ukuyiqonda kuphela.
Itekhnoloji yokuvavanya umbane wefoto yitekhnoloji entsha eyimfuneko kwisayensi yanamhlanje, ukuphuculwa kwelizwe kunye nobomi babantu, bubuchwepheshe obutsha obudibanisa umatshini, ukukhanya, umbane kunye nekhompyuter, kwaye bobona buchwepheshe bunokubakho bolwazi.
Okwesithathu, ukubunjwa kunye neempawu zenkqubo yokukhangela i-photoelectric
Ngenxa yobunzima kunye nokuhlukahluka kwezinto ezivavanyiweyo, isakhiwo senkqubo yokufumanisa ayifani. Inkqubo yokufumanisa i-elektroniki ngokubanzi yenziwe ngamacandelo amathathu: inzwa, isilungisi somqondiso kunye nekhonkco eliphumayo.
I-sensor yi-converter yesignali kwi-interface phakathi kwento evavanyiweyo kunye nenkqubo yokufumanisa. Ikhupha ngokuthe ngqo ulwazi olulinganisiweyo kwizinto ezilinganisiweyo, ivakalelwa utshintsho, kwaye iguqule kwiiparamitha zombane ezilula ukulinganisa.
Iimpawu ezichongiweyo zizivamvo zidla ngokuba ziimpawu zombane. Ayinakuhlangabezana ngokuthe ngqo neemfuno zemveliso, idinga utshintsho olongezelelweyo, ukuqhutyelwa phambili kunye nokuhlalutya, oko kukuthi, ngokusebenzisa i-signal conditioning circuit ukuguqula ibe ngumqondiso oqhelekileyo wombane, imveliso kwikhonkco yokuphuma.
Ngokwenjongo kunye nefom yemveliso yenkqubo yokufumanisa, ikhonkco lokuphuma libonisa ngokukodwa kunye nesixhobo sokurekhoda, unxibelelwano lwedatha yonxibelelwano kunye nesixhobo sokulawula.
Isiphaluka sokumisa umqondiso we-sensor sichongwa luhlobo lwenzwa kunye neemfuno zesignali yokuphuma. Abenzi boluvo abahlukeneyo banemiqondiso eyahlukeneyo yemveliso. Isiphumo senzwa yolawulo lwamandla lutshintsho lweeparamitha zombane, ekufuneka ziguqulwe zibe yinguqu yombane yisekethe yebhulorho, kunye nesiphumo sophawu lwe-voltage yesekethe yebhulorho sincinci, kwaye umbane wemowudi eqhelekileyo mkhulu, owufunayo. ukuba yandiswe sisixhobo sokukhulisa isixhobo. I-voltage kunye neempawu zangoku eziphuma kwi-sensor yokuguqula amandla ngokubanzi ziqulethe imiqondiso emikhulu yengxolo. Isekethe yokucoca iyafuneka ukukhupha imiqondiso eluncedo kunye nokuhluza imiqondiso engenamsebenzi yengxolo. Ngaphezu koko, i-amplitude ye-voltage signal output yi-sensor yamandla ngokubanzi iphantsi kakhulu, kwaye inokwandiswa sisixhobo sokukhulisa isixhobo.
Xa kuthelekiswa ne-electronic carrier carrier, i-frequency ye-photoelectric system carrier yongezwa ngee-odolo ezininzi zobukhulu. Olu tshintsho kumyalelo we-frequency yenza ukuba inkqubo ye-photoelectric ibe nenguqu yekhwalithi kwindlela yokuqonda kunye nokutsiba okusemgangathweni kumsebenzi. Ikakhulu ibonakaliswe kumthamo wokuthwala, isisombululo se-angular, isisombululo soluhlu kunye nesisombululo se-spectral siphuculwe kakhulu, ngoko sisetyenziswa ngokubanzi kwiinkalo zeshaneli, i-radar, unxibelelwano, isikhokelo esichanekileyo, ukuhamba, ukulinganisa kunye nokunye. Nangona iifom ezithile zenkqubo ye-photoelectric esetyenzisiweyo kwezi zihlandlo zihluke, zinento efanayo, oko kukuthi, zonke zinekhonkco lomthumeli, i-channel optical kunye ne-optical receiver.
Iinkqubo ze-Photoelectric zihlala zihlulwe zibe ngamacandelo amabini: asebenzayo kunye ne-passive. Kwinkqubo ye-photoelectric esebenzayo, i-transmitter optical iqulunqwe ikakhulu ngumthombo wokukhanya (njenge-laser) kunye ne-modulator. Kwi-passive photoelectric system, i-optical transmitter ikhupha i-thermal radiation ukusuka kwinto ephantsi kovavanyo. Iitshaneli ze-Optical kunye nabamkeli be-optical ziyafana zombini. Into ebizwa ngokuba yi-optical channel ibhekiselele kwi-atmosfera, indawo, ngaphantsi kwamanzi kunye ne-fiber optical. I-receiver optical isetyenziselwa ukuqokelela isiganeko se-optical signal kwaye siyiqhube ukubuyisela ulwazi lomthwali we-optical, kubandakanywa iimodyuli ezintathu ezisisiseko.
Ukuguqulwa kwe-Photoelectric ngokuqhelekileyo kufezekiswa ngeendlela ezahlukeneyo zamacandelo kunye neenkqubo zokukhanya, usebenzisa izibuko ezizicaba, i-slits optical, iilensi, iiprism ze-cone, i-polarizers, iipleyiti zamaza, iipleyiti zekhowudi, i-grating, i-modulators, i-optical imaging systems, i-optical interference systems, njl. ukufezekisa ukuguqulwa okulinganisiweyo kwiiparameters ze-optical (i-amplitude, i-frequency, isigaba, i-polarization state, utshintsho lwe-propagation direction, njl.). Ukuguqulwa kweefoto zombane kufezekiswa ngezixhobo ezahlukeneyo zokuguqula iifoto zombane, njengezixhobo zokubona umbane, izixhobo zekhamera yeefoto zombane, izixhobo ezishushu zombane kunye nokunye.
