Isithwebuli zeminwe njengendlela yokuthola ukuqinisekiswa lomsebenzisi

Kuze kube manje, lo computerization emphakathini kusenza sifune izindlela ezahlukene ukuze kukhawulwe ukufinyelela ukwaziswa okugcinwe kuyi-computer. Ngaphezu kwalokho, ukugunyazwa umsebenzisi futhi uhlelo ukugunyaza iphasiwedi ingenye ezivame kakhulu, nakuba has nemiphumela ethile engathandeki eziningi. Esikhundleni ukuvikelwa kwephasiwedi kungaba ukuqinisekiswa lomsebenzisi nemingcele yebhayomethrikhi, njengemoto zeminwe. Futhi kuthatha kuphela isithwebuli zeminwe kanye ne-software ezihambisana, eza kudivayisi.

Uyini isithwebuli zeminwe

isithwebuli zeminwe umshini lifundza zeminwe isithombe nazo zonke izici zawo ngesimo iminwe, futhi adlulisele umphumela scan ukuze isofthiwe. isicelo ezikhethekile eqhathanisa isithombe nge imodeli wadala at the stage of iphasiwedi yebhayomethrikhi.

Izinhlobo zeminwe scanner

Zonke scanner zeminwe, okwamanje esetshenziswa, kungenziwa labizwa ngamaqembu amathathu, isekelwe esimisweni somzimba wokusebenza:

- Semiconductor (Silicon);

- Optical;

- ultrasound.

Semiconductor scanner

Lolu hlobo lwe-Enani ithola isithombe esekelwe Semiconductor izakhiwo ukuthi ukushintsha kule ndawo contact ka zeminwe izithombe kanye isithwebuli. Ukusebenza lolu hlobo amadivayisi ukuskena angase alale ubuchwepheshe eziningana:

- Capacitive scanner. Ukusebenza scanner sinjalo umphumela ukuthi amandla e-PN-ushintsho kudivayisi Semiconductor kuyahlukahluka phezu contact zeminwe emikhulu kanye izakhi Semiconductor we matrix.

- a scanner azwela umfutho. I isithwebuli zeminwe yalolu hlobo usebenza usebenzisa afanayo olukhethekile izakhi piezoelectric. Lapho umunwe kuyinto nabo matrix, lamagquma nibeka ingcindezi phezu kwayo, ukucindezeleka, ngokulandelana, akukho. Kususelwa ukucindezela kwendikimba matrix, futhi kwakhiwa isithombe.

- Thermo-scanner. Iskena amadivayisi zaloluhlobo zinzima izinzwa esetshenziswa kwala maphuzu pyroelectric. Lezi izinzwa ukurekhoda umehluko lokushisa, ngemva kwalokho-ke iguqulwe ibe zinamandla.

- RF scanner. Izikena yalolu hlobo aqukethe mikroantenn ukuthi ukhiqize isignali enganamandla, futhi kuphendulwa wathola zeminwe value kusuka electro-ngesisusa amandla elakhiwe yokugcina zeminwe isithombe.

- Ukwethula Thermo-scanner. Ofana Thermo-scanner. Umehluko wukuthi kumele ubambe umunwe wakho phezu ukuskena, futhi azisebenzi ke.

- Capacitive isithwebuli wemishini emincane. Ubuchwepheshe ngokukhiqiza zeminwe isithombe kuyafana e capacitance, kodwa indlela kulungiselelwa ungachazwa ukuthi umunwe wenziwa phezu ukuskena.

- RF isithwebuli wemishini emincane. Umgomo we operation alamathuluzi kuyafana kule amadivayisi e-radio-imvamisa, kodwa indlela yokususa sithombe isicelo zeminwe kudivayisi, futhi ubambe umunwe wakho yonkana ubuso bayo.

scanner optical

I isithwebuli zeminwe yalolu hlobo ithola umunwe isithombe ngokusebenzisa indlela optical. Ukusebenza amadivayisi zaloluhlobo zinzima ubuchwephese obehlukahlukene

- FTIR-scanner. Lezi amadivayisi zisebenzisa yangaphakathi kuveza nomphumela kuphazamisekile.

- fiber optic scanner. Inzwa zeminwe kuyinto matrix fibre optical, lapho fibre ngasinye yakhiwa photocell.

- scanner Electro-optical. Ukulungiselela isithombe livela polymer electrooptic nesebenzisa ungqimba ukukhanya-likhipha.

- Optical wemishini emincane Enani. Lolu hlobo imishini kuyinto kumadivayisi intuthuko fibre lapho imaging kuyadingeka ukuze afeze umunwe wakho yonkana kwamanzi futhi lingabhekiseli kulo.

- Roller scanner. Ukuze uthole isithombe udinga ubambe umunwe wakho roller, lapho enza izithombe umunwe ngamaphetheni papillary.

- Non-contact scanner. umunwe scan wenziwa ngendlela yokuxhumana. Umunwe lisetshenzisiwe imbobo lapho zikhanyiswa imithombo eminingi, bese ikhamera esakhelwe ithumba umfanekiso umunwe.

ultrasound scanner

Lolu hlobo idivayisi aqalaze kobuso amagagasi ultrasonic emunweni, futhi isekelwe ibanga elinganisiwe amagagasi kubonakala kusukela ayimigodi kanye emisebenzi yakhiwa isithombe. Lolu hlobo idivayisi ihlukile ngenhla bahlola ukuthi ukuskena yi kuyinto engcono.
