Ii-Fotoelectric Detectors zinamandla njani kwihlabathi lethu elingabonakaliyo
Ngaba ukhe uzibuze ukuba i-smartphone yakho ihlengahlengisa njani ukukhanya ngokuzenzekelayo, oomatshini basefektri “bona” iimveliso ezibhabhayo, okanye iinkqubo zokhuseleko ziyazi ukuba kukho umntu osondelayo? Igorha elingavunywanga emva kwezi zenzo sisikhangeli sombane – isixhobo esijika ukukhanya sibe bubulumko obusebenzayo.
Ke ngokuNgokuchanekileyoNgaba i-Photoelectric Detector iyayenza?
Kwisiseko sayo, i-photoelectric detector sisixhobo esoiguqula imiqondiso yokukhanya (iifotoni) ibe yimiqondiso yombane (yangoku okanye yombane). Yicinge njengomguquleli omncinci, obona utshintsho ekukhanyeni - nokuba i-beam ivaliwe, ibonakaliswe, okanye i-intensitet shifts - kwaye ngokukhawuleza iguqule loo nkcazelo ibe yimveliso yombane enokuthi iqondwe ngoomatshini, iikhompyutha, okanye iinkqubo zokulawula. Obu buchule busisiseko, busekelwe ikakhulu kwiisiphumo sombane(apho ukukhanya kubetha imathiriyeli ethile kukhulula ii-electron), kuwenza abe “amehlo” aguquguqukayo kwizicelo ezingenakubalwa.
Zisebenza Njani Ezi "Sensors Light" eneneni?
Uninzi lwee-detectors zefoto zombane zineendawo ezintathu eziphambili:
- Umthombo wokukhanya (Emitter):Ngokuqhelekileyo i-LED (ebonakalayo ebomvu, eluhlaza, okanye i-infrared) okanye i-laser diode, ithumela i-beam egxininisiweyo yokukhanya.
- Umamkeli:Ngokuqhelekileyo i-photodiode okanye i-phototransistor, eyilwe ngobunono ukubona ukukhanya okukhutshiweyo kunye nokuguqula ubukho bayo, ukungabikho, okanye ukuguqulwa kokuqina kumbane.
- ISekethe yoFundo:Ubuchopho obusebenzisa umqondiso womamkeli, ukuhluza ingxolo kunye nokubangela imveliso ecocekileyo, ethembekileyo (efana nokuvula / ukuvala iswitshi okanye ukuthumela isignali yedatha).
Babona izinto okanye utshintsho besebenzisa iindlela ezahlukeneyo "zokubona":
- Nge-Beam (Ugqithiso):I-Emitter kunye nomamkeli bajongana. Into iyabhaqwa xa iyiyoiibhlokoukukhanya. Inikezela ngoluhlu olude kakhulu (10+ yeemitha) kunye nokuthembeka okuphezulu.
- Ukubuyisela umva:I-Emitter kunye nomamkeli bakwiyunithi efanayo, ejongene nesibonisi esikhethekileyo. Into iyabhaqwa xa iyiyoikhefuumtha obonisiweyo. Ulungelelwaniso olula kune-beam kodwa lunokuqhathwa zizinto ezibengezela kakhulu .
- I-Diffuse Reflective:I-Emitter kunye nomamkeli bakwiyunithi enye, bekhomba ngokubhekiselele ekujoliswe kuko. Into ifunyenwe xa iibonakalisaukukhanya okukhutshiweyo kubuyela kumamkeli. Ayifuni isibonisi esahlukileyo, kodwa ukubonwa kuxhomekeke kumphezulu wento .
- Uxinzelelo lwangasemva (BGS):Uhlobo losasazo olukrelekrele. Isebenzisa unxantathu, itkuphelaIbhaqa izinto phakathi koluhlu oluthile, olucwangcisiweyo lomgama, ukungahoyi nantoni na engaphaya kwayo okanye ekufutshane kakhulu emva kwethagethi.
Kutheni Zikho Kuyo Yonke Indawo? Izinto eziluncedo ezingundoqo:
Izixhobo zokubona umbane zilawula imisebenzi emininzi yokuva kuba zibonelela ngeenzuzo ezizodwa:
- Ukuziva ungaqhagamshelwanga:Akuyomfuneko ukuba bachukumise into, ukuthintela ukunxiba kunye nokukrazula kuzo zombini inzwa kunye nezinto ezibuthathaka.
