Intshayelelo yetekhnoloji yovavanyo lwe-photoelectric
Iteknoloji yokubhaqwa kwefotoelectric yenye yezona teknoloji ziphambili zobuchwepheshe bolwazi lwefotoelectric, eziquka ikakhulu iteknoloji yokuguqulwa kwefotoelectric, ukufunyanwa kolwazi lwe-optical kunye neteknoloji yokulinganisa ulwazi lwe-optical kunye neteknoloji yokucubungula ifotoelectric yolwazi lokulinganisa. Ezifana nendlela yefotoelectric yokufezekisa iintlobo ngeentlobo zokulinganisa ngokomzimba, ukukhanya okuphantsi, ukulinganisa ukukhanya okuphantsi, ukulinganisa kwe-infrared, ukuskena ukukhanya, ukulinganisa ukulandelela ukukhanya, ukulinganisa i-laser, ukulinganisa i-optical fiber, ukulinganisa umfanekiso.
Iteknoloji yokubona i-photoelectric idibanisa iteknoloji ye-optical kunye neteknoloji ye-elektroniki ukulinganisa ubungakanani obahlukeneyo, obuneempawu ezilandelayo:
1. Ukuchaneka okuphezulu. Ukuchaneka komlinganiselo we-photoelectric yeyona ndlela iphezulu kuzo zonke iintlobo zokulinganisa. Umzekelo, ukuchaneka kobude bokulinganisa nge-laser interferometry kunokufikelela kwi-0.05μm/m; Indlela yokulinganisa i-Angle nge-grating moire fringe method inokufezekiswa. Isisombululo sokulinganisa umgama phakathi komhlaba nenyanga ngendlela yokulinganisa nge-laser sinokufikelela kwi-1m.
2. Isantya esiphezulu. Ukulinganisa i-photoelectric kuthatha ukukhanya njengesixhobo, kwaye ukukhanya sesona santya sikhawulezayo sokusasaza phakathi kwazo zonke iintlobo zezinto, kwaye ngokungathandabuzekiyo sesona sikhawulezayo sokufumana nokudlulisa ulwazi ngeendlela zokukhanya.
3. Umgama omde, ububanzi. Ukukhanya yeyona ndlela ifanelekileyo yokulawula kude kunye ne-telemetry, efana nokukhokela izixhobo, ukulandelela nge-photoelectric, i-telemetry kamabonakude njalo njalo.
4. Ukulinganisa okungangqamananga. Ukukhanya kwinto elinganisiweyo kunokuthathwa njengokungabi namandla okulinganisa, ngoko ke akukho kungqubana, ukulinganisa okunamandla kunokufezekiswa, kwaye yeyona ndlela isebenzayo kwiindlela ezahlukeneyo zokulinganisa.
5. Ubomi obude. Ngokwethiyori, amaza okukhanya awagugi, logama nje ukuphinda kusetyenziswe kakuhle, kungasetyenziswa ngonaphakade.
6. Ngobuchule obuqinileyo bokucubungula ulwazi kunye nezakhono zokubala, ulwazi oluntsonkothileyo lunokucutshungulwa ngaxeshanye. Indlela ye-photoelectric ikwalula ukuyilawula nokugcina ulwazi, kulula ukuyenza ngokuzenzekelayo, kulula ukuyiqhagamshela kwikhompyutha, kwaye kulula ukuyenza kuphela.
Iteknoloji yovavanyo lwe-photoelectric yiteknoloji entsha ebalulekileyo kwisayensi yanamhlanje, ukuphuculwa kwesizwe kunye nobomi babantu, yiteknoloji entsha edibanisa oomatshini, ukukhanya, umbane kunye nekhompyutha, kwaye yenye yezona teknoloji zolwazi zinokwenzeka.
Okwesithathu, ukwakheka kunye neempawu zenkqubo yokubona i-photoelectric
Ngenxa yobunzima nokwahluka kwezinto ezivavanyiweyo, ulwakhiwo lwenkqubo yokufumanisa alufani. Inkqubo yokufumanisa ye-elektroniki ngokubanzi yenziwe ngamacandelo amathathu: i-sensor, i-signal conditioner kunye ne-output link.
Isensor sisixhobo sokuguqula isignali kwindawo ephakathi kwento evavanyiweyo kunye nenkqubo yokufumanisa. Sikhupha ngqo ulwazi olulinganisiweyo kwinto elinganisiweyo, siva utshintsho lwayo, size siyiguqule ibe ziiparameter zombane ezilula ukuzilinganisa.
Imiqondiso efunyenwe zizinzwa ngokubanzi ziimpawu zombane. Ayikwazi ukuhlangabezana ngqo neemfuno zemveliso, ifuna utshintsho olongezelelweyo, ukucutshungulwa kunye nohlalutyo, oko kukuthi, ngokusebenzisa isekethe yokulungisa isignali ukuyiguqula ibe sisignali yombane eqhelekileyo, imveliso kwikhonkco lemveliso.
Ngokwenjongo kunye nohlobo lwemveliso yenkqubo yokuchonga, ikhonkco lemveliso ikakhulu sisixhobo sokubonisa nokurekhoda, ujongano lonxibelelwano lwedatha kunye nesixhobo solawulo.
Isekethe yokulungisa isignali yesensor imiselwa luhlobo lwesensor kunye neemfuno zesignali yokukhupha. Iisensor ezahlukeneyo zinezibonakaliso zokukhupha ezahlukeneyo. Isiphumo sesensor yokulawula amandla kukutshintsha kweeparamitha zombane, ekufuneka ziguqulwe zibe lutshintsho lwevolthi yisekethe yebhulorho, kwaye isiphumo sesignali yombane yesekethe yebhulorho sincinci, kwaye ivolthi yemowudi eqhelekileyo inkulu, ekufuneka inyuswe yi-amplifier yesixhobo. I-voltage kunye nesignali zangoku eziphuma yi-sensor yokuguqula amandla zihlala ziqulathe imiqondiso yengxolo enkulu. Isekethe yesihluzo iyafuneka ukuze kukhutshwe imiqondiso eluncedo kwaye kuhluzwe imiqondiso yengxolo engenamsebenzi. Ngaphezu koko, ubukhulu besiphumo sesignali yombane yi-sensor yamandla ngokubanzi buphantsi kakhulu, kwaye bunokwandiswa yi-amplifier yesixhobo.
Xa kuthelekiswa ne-electronic system carrier, i-frequency ye-photoelectric system carrier yonyuswa ngama-odolo amaninzi obukhulu. Olu tshintsho kwindlela ye-frequency order lwenza ukuba inkqubo ye-photoelectric ibe notshintsho olusemgangathweni kwindlela yokufezekisa kunye nokunyuka okusemgangathweni kumsebenzi. Ngokuyintloko ibonakaliswa kumthamo we-carrier, isisombululo se-angular, isisombululo sobubanzi kunye nesisombululo se-spectral ziphuculwe kakhulu, ngoko ke isetyenziswa kakhulu kwicandelo le-channel, i-radar, unxibelelwano, isikhokelo esichanekileyo, ukuhamba, ukulinganisa njalo njalo. Nangona iintlobo ezithile zenkqubo ye-photoelectric ezisetyenziswa kwezi zihlandlo zahlukile, zinempawu ezifanayo, oko kukuthi, zonke zinekhonkco le-transmitter, i-optical channel kunye ne-optical receiver.
Iinkqubo ze-photoelectric zihlala zahlulwe zibe ziindidi ezimbini: ezisebenzayo nezingasebenziyo. Kwinkqubo ye-photoelectric esebenzayo, i-optical transmitter yenziwe ikakhulu ngumthombo wokukhanya (njenge-laser) kunye ne-modulator. Kwinkqubo ye-photoelectric engasebenzisiyo, i-optical transmitter ikhupha i-thermal radiation evela kwinto evavanywayo. Iitshaneli ze-Optical kunye nee-optical receivers ziyafana kuzo zombini. I-optical channel ebizwa ngokuba yi-optical channel ibhekisa kakhulu kwi-atmosphere, kwindawo, phantsi kwamanzi kunye ne-optical fiber. I-optical receiver isetyenziselwa ukuqokelela isignali ye-optical yesiganeko kunye nokuyicubungula ukuze ifumane ulwazi lomthwali we-optical, kubandakanya iimodyuli ezintathu ezisisiseko.
Ukuguqulwa kwe-Photoelectric kudla ngokufezekiswa ngokusebenzisa izixhobo ezahlukeneyo ze-optical kunye neenkqubo ze-optical, kusetyenziswa izibuko ezisicaba, ii-optical slits, iilensi, ii-cone prisms, ii-polarizers, ii-wave plates, ii-code plates, ii-grating, ii-modulators, iinkqubo ze-optical imaging, iinkqubo zokuphazamiseka kwe-optical, njl.njl., ukufezekisa ukuguqulwa okulinganisiweyo kwi-optical parameters (i-amplitude, i-frequency, i-phase, imeko ye-polarization, utshintsho lwendlela yokusasazeka, njl.njl.). Ukuguqulwa kwe-Photoelectric kwenziwa zizixhobo ezahlukeneyo ze-photoelectric conversion, ezifana nezixhobo zokufumanisa i-photoelectric, izixhobo zekhamera ye-photoelectric, izixhobo ze-photoelectric thermal njalo njalo.
