Inzululwazi edumileyo yezinzwa zeskena yomnwe

Itekhnoloji, isoftware kunye nezixhobo ze-Hardware zeskena zomnwe ziphuhliswe ngokuqhubekayo. Okwangoku, zininzi iintlobo zezinzwa ezisetyenziswa emnyango emarikeni, kwaye iimpawu zazo zahlukile kwaye imisebenzi yazo ikwahlukile. Abanye abathengi abatshixa batsho ukuba zininzi iintlobo zescriprint yeskena zangaphantsi kwaye azikwazi ukufumana umahluko. Ngesi sizathu, uphando lweskena lomnwe ocekeceke u-pro wamema iingcali ezifanelekileyo kwishishini ukuba azise ulwazi olufanelekileyo malunga nezinzwa zescarrint yescanrint yomnwe. Iindidi zeenqutyana zeScriprint Handerrint okwangoku, ikakhulu ziintlobo ezintathu zenzwa kwimakethi yeskena yomnwe: infrared, i-lidar (i-tof, i-millime ye-radar ye-millime.

1. I-infrafrence Umgaqo weenzwa ze-infrared kukusebenzisa i-inframids torming to i-E-i-i-i-i-i-i-i-i-i-e-i-i-i-i-i-ikhrayile kwi-angle ethile kwi-engile, kwaye abamkeli bafumana imiqondiso kwikona ethile. Umgama ovuthayo umiselwa ngokokuhambisa kunye nee-angles. Izinzwa ze-infrared zisetyenziswa ngokubanzi kwaye zinenani elikhulu lezicelo ezisezantsi kumayeza, emkhosini, okusingqongileyo kunye namanye amasimi. Ziyinzwa eninzi kakhulu, enjengeqondo eliqhelekileyo lobushushu, imifanekiso ye-thermal ye-thermal, njl.njl. Kodwa kwangaxeshanye, umgama ongumlinganiso we-infrared kunye nokuchaneka kwahlwempuzekile, kwaye kukho iimfuno zombala wento elinganayo. Inobuthathaka kumhlophe kwaye ingakhathalelwanga ukuba ibe mnyama (oko kukuthi, ukukhanya kuncitshiswe ngokulula ngumnyama kwaye kungabi lula ukubanjwa ngumamkeli).
2. I-Lidar idar inssors ihlulwe ikakhulu ibe ziindidi ezimbini, i-tof enye ye-tof kunye nokukhanya okwakhiwe. Umgaqo-nkqubo we-TOF kukuba i-laser ye-laser ikhupha i-infrared laser, kwaye umamkeli ubala umahluko wexesha lokuphuma nokwamkelwa, kwaye umgama unokubalwa ngokwesantya sokukhanya. Ukukhanya okucwangcisiweyo kukuba i-laser ye-laser ikhupha indawo yokukhanya, kwaye umgama umiselwe ngokubala ubungakanani bendawo yokukhanya. I-lidar inomlinganiso wokulinganisa ophezulu, kwaye kwangaxeshanye, inokufumana ulwazi olunzulu lwento elinganiswa ngokuchaneka okuphezulu. Kodwa kwangaxeshanye, i-lidar ixabisa kakhulu kwaye ichaphazeleke ngokulula kwizinto zokusingqongileyo, ezinjengokukhanya kwelanga, imvula, inkungu, njl njl.
3. I-Millimeter Wave ye-millimer millimeter wave ibhekisa kwibhendi enesisu lokusebenza kwi-1 ukuya kwi-10 mm. Umgaqo kukuba udluliso luphawula amaza emiliphetha, kwaye umamkeli ubala umgama ngomphumo we-doppler. Iziphumo ze-doppler zibhekisa kutshintsho kwi-wavelength ye-radiation yento ngenxa yokuhamba komthombo wamaza kunye nombukeli. Phambi komthombo wamaza oshukumayo, i-wave inyanzelekile, i-wavelength yenziwe isifutshane, kwaye i-frequency iphakame; Emva komthombo wamaza oshukumayo, i-wavelength ingqokelela ixhomekeke kwaye i-frequency iba phantsi; Ukuphakama kwesantya somthombo wamaza, umphumo omkhulu. Ngokwamanqanaba obomvu (okanye oluhlaza okwesibhakabhaka) lwamaza, isantya somthombo wamaza ohamba ngendlela yokujonga abalwe.
