A line scan lensiyi lenzi yakakosha iyo inonyanya kushandiswa mumutsara scan kamera. Inoita yakakwirira-kumhanya scanning imaging mune imwe dimension. Iyo yakasiyana neyechinyakare kamera lenses uye inowanzo shandiswa mundima yeindasitiri.
Ndeipi iyo inoshanda musimboti weline scanlenzi?
Nheyo yekushanda yeline scan lens inonyanya kuenderana neline scan technology. Paunenge uchishanda, iyo line scan lens inotarisisa iyo sample surface mutsara nemutsara uye inounganidza ruzivo rwechiedza chemutsara wega wega wemapikiseli kubatsira iyo line scan lens kutora mufananidzo wesample yese pane kutora mufananidzo wese kamwechete.
Kunyanya, iyo yekushanda musimboti weiyo mutsara scan lens ine akati wandei matanho:
Optical imaging:Chiratidzo chechiedza chemuenzaniso wekuongororwa chinotorwa nemutsara-ne-mutsara photosensitive zvinhu pamutsara wekutarisa lens uye inoshandurwa kuita masaini emagetsi.
Line-by-line scanning:Iyo mutsara-ne-mutsara photosensitive element inotarisa kubva kumusoro kusvika kuzasi kwemuenzaniso pane imwe kumhanya, ichishandura ruzivo rwechiedza chemutsara wega wega kuita chiratidzo chemagetsi.
Signal processing:Mushure mekugadzirisa, chiratidzo chemagetsi chinoshandurwa kuita chiratidzo chedhijitari yekugadzira mufananidzo.
Kusona mufananidzo:batanidza masaini edhijitari emutsara wega wega kuti pakupedzisira ugadzire mufananidzo wemuenzaniso wese.
Nheyo yekushanda yeline scan lens
Ndeapi ma paramita anofanirwa kutariswa kune yeline scan lenzi?
Iyo parameters yeline scan lenzizvine hukama zvakanyanya kune zvakasiyana zvinodiwa uye mamiriro ekushandisa. Iyo inotevera parameter inofanirwa kutariswa pane:
Resolution
Kugadziriswa kweiyo line scan lens kazhinji ndiyo yekutanga metric yekunetsekana. Iyo yakakwirira yekugadzirisa, iyo yakakwirira yemufananidzo kujeka, iyo ine hukama nehuwandu hwepixels munzvimbo yekufungidzira uye saizi yechinhu chekufungidzira.
Aperture
Saizi yeaperture inodzora huwandu hwechiedza chinopinda mulenzi, zvichikanganisa kupenya kwemufananidzo we lens uye nguva yekuratidzwa kwefirimu. Gombe hombe rinogona kuvandudza kunaka kwemufananidzo kana richishandiswa munzvimbo dzakadzika, asi rinogona kuderedza kudzika kwemhando.
Focus range
Kutarisisa (focus range) zvinoreva nhambwe inogona kupfura lenzi. Kazhinji, iyo yakafara ndiyo iri nani, uye yakafara zvinoreva kuti inogona kupfura zvimwe zvinhu zvehurefu hwakasiyana hwakatarisana.
Image urefu
Kureba kwemufananidzo kunoreva kureba kwenzvimbo yekufungidzira lenzi munzira yekutarisa. Kureba kwemufananidzo kwakakura kunoda kukurumidza kutarisisa kumhanya, izvo zvinozokonzera kukurumidza kwekufungidzira kwepamusoro uye chiyero chepamusoro chekufambisa data.
Tarisa pamhando yemufananidzo
Imaging quality
Hunhu hwekufungidzira hunogona kuyerwa nemaparamendi akadai se lateral resolution, chiratidzo-ku-ruzha reshiyo, uye kuzara kwemavara. Kazhinji, yakakwira lateral resolution, chiratidzo-ku-ruzha reshiyo, uye kuzara kwemavara zvinoreva mhando yepamusoro yemufananidzo.
Lens saizi uye uremu
Saizi uye uremu zvinogona kukanganisa kushandiswa kweline scan lenzimune mamwe maapplication. Naizvozvo, saizi uye huremu hwelenzi inodawo kutariswa zvinoenderana neakasiyana mashandisirwo mamiriro.
Pfungwa dzekupedzisira:
Kana iwe uchifarira kutenga akasiyana marudzi emalenzi ekutarisa, kuongorora, drones, smart imba, kana chero imwe kushandiswa, isu tine zvaunoda. Bata nesu nhasi kuti udzidze zvakawanda nezve malenzi edu uye zvimwe zvishongedzo.
