Ukuskena iilensizisetyenziswa ngokubanzi kwi-AOI, uhlolo oluprinta, uhlolo lwelaphu olungafunekiyo, uhlolo lwesikhumba, umkhondo we-Railway, ukuhlolwa kunye nokuhlelwa kombala kunye namanye amashishini. Eli nqaku lizisa intshayelelo kwiilensi zeskena.

Intshayelelo kwi-Scan Scan Ilensi

1) Umxholo weScan Scan:

I-lens ye-CCD ye-CCD ye-CCD yelensi ye-FARMON ye-FARY CARY CARY CREGLES ihambelana nobungakanani bemifanekiso, ubungakanani be-Pixel, kwaye zinokusetyenziswa kuhlolo oluchanekileyo lokuchaneka.

2) Iimpawu ze-Scan Ilensi:

1. Yenzelwe ngokukodwa izicelo eziphezulu zokusombulula iingxaki, ukuya kwi-12k;

2. Elona nqaku lihambelana nengcinga ezihambelana nayo yi-90mm, usebenzisa ikhamera ye-scad ye-scad;

3. Isisombululo esiphezulu, ubuncinci be-pixel ukuya kwi-5m;

4. Ixabiso eliphantsi lokugqwetha;

I-5. Ukuqiniswa kwe-0.2x-2.0x.

Ukuqwalaselwa ngokukhetha i-scan yeskena

Kutheni le nto kufuneka siqwalasele ukhetho lwelensi xa ukhetha ikhamera? Ikhamera ye-scads eqhelekileyo ngoku inezigqibo ze-1K, 2K, i-4K, i-7K, i-7K, kunye ne-14K, i-1k, i-1kx10m) ukuya kwi-86.016mm (12kx7um) iyahluka.

Ngokucacileyo, i-Center ye-C ukude ikuhlangabezane neemfuno, kuba i-C i-C iqhagamshela kuphela i-chips ngesayizi eyi-22mm, yi-intshi eyi-1.33. Ujongano lwekhamera ezininzi yi f, m42x1, m72x0.75, njl. Njl.

I-1) I-DISTALICATION SPARK (β, isimanga)

Nje ukuba isisombululo sekhamera kunye nobungakanani be-pixel simiselwe, ubungakanani besinweyo bunokubalwa; Ubungakanani be-sensor bahluleke yindawo yokujonga (i-FOV) ilingana nokukhuliswa kokukhanya. β = ccd / fov

2) Isinxibelelanisi (iNtaba)

Kukho ikakhulu C, M42X1, F, T2, Leica, M72X0.75, njl njl.

I-3) umgama weflethi

Ukugxila kwangasemva kubhekisa kumgama ukusuka kwi-Display kwi-Display kwi-Chineses kwi-chip. Yiparamitha ebaluleke kakhulu kwaye igqitywe ngumvelisi wekhamera ngokwendlela yayo yokukhanya. Iikhamera ezivela kubavelisi abahlukeneyo, kwanembono enye, zinokuba nejoliso eyahlukileyo.

4) MTF

Ngolwazi lokukhanya, isinxibelelanisi, kunye nokugxila kwangasemva, umgama osebenzayo kunye nobude be-ring edibeneyo bubalwa. Emva kokukhetha ezi, kukho enye ikhonkco elibalulekileyo, elikukubona ukuba ixabiso le-MTF lilungile ngokwaneleyo? Uninzi lweenjineli ezibonakalayo aziyiqondi i-MTF, kodwa kwiilensi eziphakamileyo, i-MTF kufuneka isetyenziselwe ukulinganisa umgangatho owahlukileyo.

I-MTF igubungela ubutyebi bolwazi olufana nolwahluko, isisombululo, rhoqo, i-chromatic ye-ofisi, njl njl. Ayisiyo kuphela umgama kunye nommandla wokujonga ihlangabezane neemfuno, kodwa umahluko weemphetho azilunganga ngokwaneleyo, kodwa nokuba kukhetha ilensi ephezulu.
