Indlela yokuhlukanisa imojuli yokuskena ibhakhodi?

Ihlukaniswa kanjani imojuli yokuskena ibhakhodi?

Abantu abaningi bayazi ukuthi i-imojuli yokuskena ibhakhodi ingahlukaniswa ngemojuli yekhodi enohlangothi olulodwa kanye nemojuli yekhodi enezinhlangothi ezimbili. Uma kunamamojula amaningi wokuskena ibhakhodi, ungathola ukuthi umthombo wawo wokukhanya uzohluka. Ngakho-ke, empeleni, imojula yokuskena ibhakhodi nayo ingahlukaniswa ibe yimojuli ye-laser kanye nemojula yokukhanya okubomvu. Okulandelayo, i-Guangzhou Yuanda izokwethula umehluko othize phakathi kwelaser nesibani esibomvu.

Imojuli yelaser ihlukile kumojula yesibani esibomvu

Umgomo wemojula yokuskena nge-laser ukudubula isibani se-laser. Iphoyinti lomthombo ngedivayisi ye-laser yangaphakathi, shaya isibonisi ngedivayisi yesakhiwo esiwumshini, bese uzulazula iphoyinti le-laser emugqeni we-laser kukhodi yebha ngokuthembela kunjini yokudlidliza, bese uyikhipha ibe yisikhangiso. Isignali yedijithali.

Imojula yokuskena ukukhanya okubomvu ivamise ukusebenzisa umthombo wokukhanya we-LED futhi iguqulelwa isignali yesithombe sikagesi ngesici se-CCD se-photosensitive.

Amamojula amaningi okuskena nge-laser ancike ekusabalaliseni ukuze ulungise umshini ukuze wenze okokusebenza, ngakho kulula ukuwenza. kulimale lapho kushwiba, futhi i-pendulum iyasuswa. Ngakho-ke, singabona kaningi ukuthi ezinye izibhamu ze-laser eziskeniwe ngemva kokuwa ziyiphoyinti., Zikhiqize ukubuyisela okuphezulu. leyo ye-laser, ukuze ukuzinza kube ngcono, futhi izinga lokukhanda lemojula yokuskena ukukhanya okubomvu liphansi kakhulu kunelemojula yokuskena nge-laser.

Isimiso esingokoqobo se-laser nokukhanya okubomvu:

Laser ibhekisela amandla emisebe evuselelwe. I-parallelism yinhle kakhulu. Manje iningi lamalambu abomvu likhanyiswa yi-LED. Ilambu elibomvu alikona lokhu esikubiza nge-infrared light. Incazelo ebonakalayo ye-infrared iwukuphuma okuzenzakalelayo kwento enamazinga okushisa.

Amaza kagesi awabonakali. Ukukhanya kwe-infrared kuhlanganisa konke ukukhanya okunobude beza obungaphezu kokukhanya okubomvu, kuyilapho i-laser ibhekisela ekukhanyeni okunobude obuthile obuthile. Azihlobene ngempela noma ziyingxenye yensimu efanayo.

I-Laser imisebe ekhiqizwa ukukhanya okukhulisiwe okukhishwa yinjabulo. I-infrared iyingxenye ye-spectrum engabonakali ngeso lenyama. Ubude begagasi bungu-0.76 kuya ku-400 microns. Kusukela kubude beza bayo namandla, kunqunywa ukukhanya okubomvu.

Ukukhanya kokungena kanye nokuvimbela ukuphazamiseka kubi kune-laser, ngakho-ke i-laser yangaphandle ingcono kunokukhanya okubomvu ekukhanyeni okunamandla.

Okulandelayo yimikhiqizo emibili efakwe ohlwini yi-laser, I-Guangzhou Yuanda, okuyimojuli yokukhanya okubomvu nemojuli ye-laser.

Mo1708 ingenye yamamojula okuskena ashumekiwe asebenza kahle kakhulu futhi aqashelwa kakhulu amakhasimende. Inama-LED amabili abomvu ukuhlinzeka ngokukhanya okuyisizayo kokuchayeka. Ingenza kube nokwenzeka ukufunda ngokushesha okuqondiwe kwekhodi yebha ngokuthembela ekukhanyeni kwayo okuyisizayo ngisho nasezimeni ezimnyama ngokuphelele. Umsebenzi wokukhanyisa ungavulwa noma ucishwe ngokusetha. Ngenxa yokuthi ukukhanyisa kusebenzisa ukukhanya okubomvu, kunomphumela omuhle wokufunda wamakhodi angewona abomvu. Kuzinhlelo zokusebenza ezikhethekile ezisebenzisa i-inki ebomvu, zama ukucisha ukukhanya kwe-mo1708 ngokwayo, futhi usebenzise okunye ukukhanya kwangaphandle okufana nokukhanya okuluhlaza ukuze uthole usizo, okungathola ukusebenza kahle kokufunda. Kuyatuswa ukucacisa ubude begagasi bomthombo wokukhanya osizayo wangaphandle ngemva kokuhlolwa kokuqhathanisa. I-Mo1708 yamukela ubuchwepheshe bokukhipha amakhodi be-uimg core besizukulwane sesihlanu obuthuthukiswe ngokuzimele, obungakwazi ukufunda ngokushesha zonke izinhlobo zamabhakhodi ekhwalithi. Izixhumi ezibonakalayo ze-USB ne-ttl232 ezinikeziwe zihlangabezana nezimfuneko zokusebenzelana ezengeziwe. Idizayini edidiyelwe yebhodi lokuqopha kanye nekhamera yehlisa ivolumu futhi ingahlangabezana nezidingo zezinhlelo zokusebenza ezihlukahlukene ezenziwe nge-miniaturized ngokwedlulele. Ithandwa kakhulu amakhasimende ezimbonini ezahlukahlukene futhi inconywa kakhulu ngabakhiqizi nabadidiyeli bedivayisi ye-R & D ephathwa ngesandla ekhaya naphesheya. Isetshenziswa kabanzi kumaphrojekthi amaningi ahlukene, iletha amandla amasha esayensi nezobuchwepheshe ekuguqulweni kwemboni yokuskena eshumekiwe!

injini yokufunda iwuhlelo lokusebenza lomkhiqizo we-OEM oluhlinzekelwe amakhasimende ngokukhethekile. Le njini yokufunda ye-CCD esebenza kahle kakhulu ihlanganisa umqoqi wesithombe nebhodi lokuqopha, ngevolumu encane nesisindo esincane. Ingashumekwa kalula kumadivayisi ahlukahlukene njengezingxenye zokufunda ibhakhodiImojula yokuskena isebenzisa ubuchwepheshe obuyinhloko obuzimele, okuhlanganisa isistimu yokubona, isistimu yokuhlanganisa ugesi wezithombe, ukubhala ngekhodi nokuqopha, ukwenza idijithali kwezithombe, uhlelo olushumekiwe, ukucutshungulwa kwezithombe kanye uchungechunge lobuchwepheshe obuphelele. Ingakwazi ukufunda wonke amakhodi asezingeni lomhlaba anohlangothi olulodwa, futhi ukusebenza kwawo kokufunda sekufinyelele ezingeni eliphezulu lamazwe ngamazweimojula yokuskena ibhakhodi
