Taw qhia
Lub lens feem ntau yog qhov tsis pom zoo tshaj plaws ntawm lub koob yees duab module. Cov neeg tsom mus rau megapixels thiab sensor rhiab heev, tab sis lub sensor zoo nrog lub lens tsis zoo yuav tseem tsim cov duab tsis zoo. Xaiv lub lens txoj cai yog qhov tseem ceeb txawm tias koj tab tom tsimembedded endoscope koob yees duab, ibautomotive soj ntsuam lub koob yees duab module,lub amicro koob yees duab modulerau cov cuab yeej kho mob. Ntawm Sincere, peb tau tsimcmos module koob yees duabkev daws teeb meem rau ntau tshaj 30 xyoo, thiab kev xaiv lens yog ib feem ntawm peb cov txheej txheem tsim. Kab lus no taug kev koj los ntawm cov ntsiab lus tseem ceeb los txiav txim siab thaum xaiv lub lens rau ib qho twglub koob yees duab module sensor.
Kauj ruam 1: Txhais koj daim ntawv thov
Ua ntej saib lub lens specs, teb cov lus nug no:
Ua haujlwm nrug: Lub koob yees duab nyob deb npaum li cas ntawm qhov kev kawm?
Field of view (FOV): Lub koob yees duab loj npaum li cas yuav tsum pom?
Kev daws teeb meem xav tau: Koj puas yuav siv lub ntsuas ntsuas siab?
Teeb pom kev zoo: Lub khw hauv pem teb, cov yeeb nkab tsaus nti sab hauv, lossis lub cev kab noj hniav?
Size txwv: Amicro koob yees duab modulerau 2 hli endoscope yog txawv heev ntawm lub koob yees duab kev ruaj ntseg.
Kauj Ruam 2: Nkag siab qhov tseem ceeb Lens Parameters
- Focal Length- Txiav txim FOV. luv focal ntev (piv txwv li, 2.8mm)=dav saib; ntev focal ntev (piv txwv li, 8mm)=nqaim saib. Rau ibendoscope koob yees duab moduleuas yuav tsum tau pom cov kab noj hniav loj, qhov luv focal ntev yog qhov zoo tshaj.
- Field of View (FOV)- Lub kaum sab xis ntawm lub lens captures. Rau ibembedded endoscope koob yees duabTshawb nrhiav qhov chaw tsis paub, qhov dav FOV (90℃-120 degree) yog qhov zoo tagnrho. Rau kev ntsuas qhov tseeb, qhov nqaim FOV (50℃-70 degree) nrog kev sib txawv tsawg yog qhov zoo dua.
- Aperture (f-npe)- Tswj lub teeb nkag. qis f-number (piv txwv li, f/2.0) cia nyob rau hauv ntau lub teeb, zoo rau lub teeb qis, tab sis txo qhov tob ntawm qhov chaw. Rau ibautomotive soj ntsuam lub koob yees duab modulesiv nyob rau hauv qhov tsaus nti engine compartments, xaiv ib tug loj aperture (f/2.0 los yog f/1.8).
- Qhov tob ntawm Field (DOF)- Ntau qhov kev ncua deb uas zoo li ntse. Endoscope koob yees duab feem ntau xav tau DOF loj vim tias kev ua haujlwm sib txawv. Fixed-focus lo ntsiab muag nrog me me aperture (siab f-number) thiab luv focal length muab DOF loj.
- Kev daws teeb meem kho qhov muag- Lub lens yuav tsum daws cov ntsiab lus txaus rau koj lub sensor. Acmos module koob yees duabnrog 5MP sensor xav tau lub lens uas tuaj yeem daws 5MP. Pairing lub siab daws teeb meem sensor nrog pheej yig, low-resolution lens nkim lub peev xwm sensor.
- Distortion- Khoov cov kab ncaj nraim. Rau kev ntsuas, xaiv cov lo ntsiab muag qis-distortion. Rau qhov dav-saib endoscopy, qee qhov kev cuam tshuam ntawm lub thoob tau txais.
- Lens Mount / Form Factor- Board lo ntsiab muag (taw tsom xam) yog me me thiab glued ncaj qha mus rau lub sensor - muaj nyob rau hauvmicro koob yees duab moduletsim. M12 lo ntsiab muag yog threaded, interchangeable, loj dua tab sis hloov tau.
Kauj Ruam 3: Sib piv Lens rau Sensor Loj
Lub lens tsim rau 1/3 " sensor muaj lub voj voog me me dua li ib qho rau 1/1.8" sensor. Siv 1/3 "lens ntawm lub sensor loj dua ua rau cov fab tsaus nti. Nco ntsoov phim lub lens lub voj voog duab rau koj.lub koob yees duab module sensorqhov loj los yog loj dua.
Kauj Ruam 4: Xav txog ib puag ncig
- Kub:Rau kev siv sab nraum zoov lossis siv tsheb, iav lo ntsiab muag nrog cov vaj tse hlau tuav qhov kub thiab txias zoo dua li yas.
- Moisture / plua plav:Rau ibautomotive soj ntsuam lub koob yees duab modulesiv nyob rau hauv ib lub chaw nres tsheb, lub lens kaw kom tsis txhob muaj pos huab.
- Kev vibration:Rau ibmicro koob yees duab moduleNyob rau hauv lub drone los yog robotic endoscope, kev ruaj ntseg lens mounting (xov xauv los yog nplaum) yog qhov tseem ceeb.
Kauj Ruam 5: Ntsuam xyuas nrog tus qauv
Tsis muaj datasheet yeej yeej qhov kev sim tiag tiag. Txiav cov qauv lo ntsiab muag (los yog ua tiav modules) thiab sim lawv nyob rau hauv koj lub teeb pom kev zoo thiab kev ua haujlwm nyob deb. Xyuas sharpness ntawm nruab nrab thiab ntug, distortion, thiab ua kom pom tseeb sib xws.
