Ruwan tabarauAna amfani da su sosai a cikin AOI, dubawa, masana'antar masana'anta da ba'a saka ba, dubawa alamar hanya, layin dogo da kuma sauran masana'antu. Wannan labarin ya kawo gabatarwar don layin tabarau na layi.

Gabatarwa zuwa Lens na layi

1) Tunani na lens bincike na layi:

Layin layi mai yawa CCD Lens ne mai yawan aikin FA don kyamarar fayilolin firam ɗin, girman pixel, kuma ana iya amfani da shi ga manyan binciken.

2) fasali na binciken lens:

1. Musamman da aka tsara don aikace-aikacen bincike mai zurfi, har zuwa 12k;

2. Matsakaicin mai nuna manufa mai manufa shine 90mm, ta amfani da kyamarar bincike mai tsayi;

3. Babban ƙuduri, mafi ƙarancin girman pixel har zuwa 5um;

4. Low murdiya murdiya;

5. Girman 0.2x-2.0x.

La'akari don zaɓar ruwan tabarau na layi

Me yasa zamuyi la'akari da zaɓin na ruwan tabarau lokacin zabar kyamarar? Common line scan cameras currently have resolutions of 1K, 2K, 4K, 6K, 7K, 8K, and 12K, and pixel sizes of 5um, 7um, 10um, and 14um, so that the size of the chip ranges from 10.240mm (1Kx10um) zuwa 86.016mm (12KX7um) ya bambanta.

Babu shakka, C Mandrace ya yi nisa daga haɗuwa da bukatun, saboda CNCURE ZAI IYA YI KYAUTA DA AIKI NA 22mm, wannan shine inci 1.3. Interface na kyamarori da yawa shine f, M42X1, M72x0.75, da sauransu lens suna daidaita da mayar da hankali na baya (frange nesa), wanda ke ƙayyade nesa na ruwan tabarau.

1) Girmanci na gani (β, daukaka)

Da zarar ƙudurin kyamara da girman pixel sun ƙaddara, ana iya ƙididdige girman firam ɗin; Girman firam ɗin ya rarrabu ta filin kallo (FOV) daidai yake da girman hangen nesa. β = ccd / Fov

2) Interface (Dutsen)

Akwai yawancin C, M42x1, F, T2, LEICA, M72x0.75, da dai sauransu bayan sun tabbatar, zaku iya sanin tsawon mahalli.

3) nisan fall

Baya mayar da hankali yana nufin nisa daga jirgin saman kamara zuwa guntu. Wani muhimmin sigar sigogi ne kuma an ƙaddara ta masana'anta kyamarar bisa ga ƙirar hanyar ta gani. Kyamarori daga masana'antun daban-daban, har ma tare da karkatar da wannan, na iya samun banbancin baya.

4) MTF

Tare da girman hangen nesa, dubawa, da baya da mayar da hankali, nesa nesa da tsawon zoben haɗin gwiwa za a iya ƙididdigewa. Bayan zabar waɗannan, akwai mahimman hanyar haɗi, wanda shine ganin idan darajar MTF tana da kyau? Yawancin injiniyan gani ba su fahimci MTF ba, amma don ruwan tabarau mai tsayi, dole ne a yi amfani da MTF don auna ingancin gani.

MTF ta rufe wani bayani kamar yadda ya bambanta, ƙuduri, mitar spatial, chromatic rauni na cibiyar da gefen tabarau a cikin cikakken bayani. Ba wai kawai aikin aiki ba ne kawai da filin kallo gamawa da bukatun, amma bambancin gefuna ba shi da kyau, amma kuma ko za a zabi ruwan tabarau mafi girma.
