Imojuli yokuskena yebhakhodi yaziwa nangokuthi Imojula Yokuskena Ibhakhodi, Injini Yokuskena Ibhakhodi, ngesiNgisi (Injini Yebhakhodi Yokuskena noma Imojuli Yebhakhodi Yokuskena). Iyingxenye yokuhlonza ewumongo esetshenziswa kakhulu emkhakheni wokuhlonza okuzenzakalelayo. Ingenye yezingxenye ezibalulekile zokuthuthukiswa kwesibili kwezikena zebhakhodi. Inemisebenzi yokuskena ibhakhodi ephelele futhi ezimele, futhi ingabhala imisebenzi ehlukahlukene yesicelo semboni njengoba kudingekile. Inosayizi omncane kanye nokuhlanganiswa okuphezulu, futhi ingashumeka kalula kumakhalekhukhwini, ama-tablet computer, amaphrinta, imishini yokuhlanganisa, imishini yezokwelapha, kanye nezinye izinto zokusebenza kuzo zonke izigaba zokuphila. Enqubweni yokuthuthukiswa, imboni yemojula yokuskena ibhakhodi emazweni angaphandle isheshe kakhulu, futhi ubuchwepheshe buvuthiwe. Ezinkulu ngokuqhathaniswa zihlanganisa i-Honeywell, i-Motorola, i-Symbol, njll.

1: Ukuhlukaniswa Imojula yokuskena ibhakhodi ingahlukaniswa ibe module yekhodi enohlangothi olulodwa kanye nemojula yekhodi enezinhlangothi ezimbili ngokuya ngokufana kokuskena, futhi ingahlukaniswa ngemojula ye-laser kanye nemojuli yokukhanya okubomvu ngokuya komthombo wokukhanya. Umehluko phakathi kwemojuli ye-laser nemojula yokukhanya okubomvu Umgomo wemojula yokuskena nge-laser ukuthi idivayisi ye-laser yangaphakathi ikhiqiza indawo yomthombo wokukhanya kwe-laser, ishaye ishidi elikhanyayo elinedivayisi yesakhiwo esiwumshini, bese ithembela kunjini yokudlidliza ukuze inyakazise iphoyinti le-laser. ibe yilayini bese ikhanya ibhakhodi, bese iyikhipha nge-AD. Isiginali yedijithali.

2:Amamojula okuskena ukukhanya okubomvu ngokuvamile asebenzisa imithombo yokukhanya ye-diode ekhipha ukukhanya kwe-LED, ancike ezintweni ze-CCD ezizwelayo, bese aziguqulela ngamasignali wesithombe sikagesi. Iningi lamamojula wokuskena we-laser ancike ekukhipheni ingcina ukuze kulungiswe umshini, ngakho-ke ivamise ukonakala kalula lapho inyakaza, bese ucezu lwe-pendulum liwe, ngakho singabona kaningi ukuthi umthombo wokukhanya oskenwe ezinye izibhamu ze-laser uba iphuzu. ngemva kokuwa. , okuholela ekusebenzeni kabusha okuphezulu kakhulu. Asikho isakhiwo somshini phakathi kwemojula yokuskena ukukhanya okubomvu, ngakho-ke ukumelana nokwehla akunakuqhathaniswa ne-laser, ngakho-ke ukuzinza kungcono, futhi izinga lokulungisa lemojula yokuskena ukukhanya okubomvu liphansi kakhulu kunelo lokuskena kwe-laser. imojula.

3:Kusukela kusimiso somzimba we-laser nokukhanya okubomvu: I-Laser ibhekisela ekukhanyeni okunamandla ashukumisayo emisebe nokuhambisana okuhle, futhi manje iningi lokukhanya okubomvu likhishwa ama-LED. Isibani esibomvu akulona uhlobo lwe-infrared esilushoyo. I-infrared echazwe yi-physics imisebe ezenzakalelayo yezinto ezinokushisa. amagagasi kagesi, angabonakali. I-infrared ihlanganisa konke ukukhanya okunamaza amaza amakhulu kunokukhanya okubomvu, kuyilapho i-laser ibhekisela ekukhanyeni okunobude obuthile. Okubili akunakho ukuxhumana okudingekayo futhi akuzona ezenkambu efanayo. I-Laser imisebe ekhiqizwa ukukhuliswa kokukhishwa okuvuselelwe. I-infrared ingxenye yesibonisi enefrikhwensi ephansi kanye ne-wavelength enkulu engakwazi ukubonwa ngeso lenyama. Ubude begagasi busuka ku-0.76 kuye ku-400 microns. Ukungena nokunqanda ukuphazamiseka kokukhanya kubi kakhulu kunelaser, ngakho-ke i-laser yangaphandle ingcono kunokukhanya okubomvu ngaphansi kokukhanya okuqinile.
