Selelekela
Theknoloji ea ho bona motlakase oa lifoto ke lejoe la motheo la mahlale a sejoale-joale le boenjiniere, le ts'ebeliso e atileng ho likhokahano, litšoantšo tsa bongaka, liindasteri le boithuto ba sesole. Motheong oa eona, theknoloji ena e fetola matšoao a optical ka lipontšo tsa motlakase, e leng ho nolofalletsang ho utloa le ho sebetsana le tlhahisoleseding e thehiloeng leseli. Har'a lisebelisoa tse fapaneng tsa ho bona motlakase oa lifoto, li-photodiode arrays (PDAs) le li-photodetector arrays (PDAs) ke mekhoa e 'meli e atileng le e bohlokoa haholo. Sengoliloeng sena se fana ka tlhahlobo ea papiso ea libopeho tsa bona, ts'ebetso, le lits'ebetso, se fana ka leseli bakeng sa ho etsa liqeto tse nang le tsebo tsa theknoloji.

1. Photodiode Array ke eng?

Photodiode ke sesebelisoa sa semiconductor se sebetsang ho ipapisitse le phello ea photoelectric. Ha li-photon li otla thepa ea semiconductor, matla a tsona a hlasimolla lielektrone, 'me li etsa lipara tsa electron-hole. Tlas'a tšimo ea motlakase e ka ntle, lijari tsena li tsamaea ka tsela, li hlahisa hona joale. Sehlopha sa photodiode se na le li-photodiode tse ngata tse ikemetseng tse hlophisitsoeng ka tlhophiso e itseng (linear or two-dimensional), tseo hangata li kopantsoeng holim'a substrate e le 'ngoe (mohlala, silicon wafer).

Sebopeho le Litšobotsi

Sebopeho se Bonolo: E na le li-unit tsa mantlha feela tsa photodiode ntle le potoloho e rarahaneng e kopaneng.

Ho Ikemela: Diode e 'ngoe le e' ngoe e arabela ka boithaopo ho matla a khanya ea ketsahalo, e ntša lets'oao la hona joale kapa la voltage le lekanang le leseli.

Kutloelo-bohloko e Phahameng: E loketse ho bona mats'oao a mabone a fokolang, joalo ka tlhahlobo ea spectral kapa laser range.

Theko e tlase: Mekhoa ea tlhahiso ea batho ba hōlileng e nolofalletsa tlhahiso ea bongata.

2. Photodetector Array ke eng?

Sehlopha sa photodetector se emela phetoho e tsoetseng pele ea li-photodiode arrays, tse kopanyang likarolo tse bonang lifoto le li-circuits tsa ts'ebetso ea matšoao ho chip e le 'ngoe. Moko oa eona o na le li-pixel tse hlophisitsoeng hantle (mohlala, li-sensor tsa CCD kapa tsa CMOS), e 'ngoe le e 'ngoe e na le ntho e nkang lifoto le li-circuits tse tšehetsang, tse nolofalletsang ho nka litšoantšo ka nako ea nnete le ts'ebetso e rarahaneng ea matšoao.

Sebopeho le Litšobotsi

Moralo o Kopantsoeng: E kopanya likarolo tsa lifoto le li-circuits tsa ts'ebetso ea matšoao (mohlala, li-amplifiers, li-converter tsa analog-to-digital).

Qeto e Phahameng ea Sebaka: Matrix a pixel a mahlakore a mabeli a nka lintlha tse qaqileng tsa setšoantšo.

Ts'ebetso ea Nako ea 'Nete:E ts'ehetsa li-algorithms bakeng sa ntlafatso ea setšoantšo le phokotso ea lerata, e loketseng maemo a matla.

Mesebetsi e mengata: E atolosoa ho bona li-infrared, ultraviolet, le lihlopha tse ling tsa spectral.

3. Tlhahlobo e Bapisang ea Photodiode Arrays le Photodetector Arrays

Lintho tse tšoanang

Molao-motheo oa Phetoho ea Motlakase oa Lifoto: Ka bobeli li itšetlehile ka phello ea photoelectric, ho fetola matla a khanyang hore e be lipontšo tsa motlakase ka thepa ea semiconductor.

Multi-Element Structure:E entsoe ka mefuta e mengata ea likaroloana tsa li-photosensitive bakeng sa ho lemoha khanya ea sebaka.

Lisebelisoa tsa Motheo:E sebelisoa ho optical sensing, taolo ea othomathiki, le masimong a tšoanang.

4. Libaka tsa Kopo

Photodiode Arrays:

Industry: Tlhokomelo ea matla a khanya mecheng ea tlhahiso, ho hlahlojoa ha barcode.

Lipatlisiso: tlhahlobo ea pectral, ho lemoha likaroloana.

Consumer Electronics:Litaolo tsa remoutu, lisensara tsa mabone a ambient.

 

Lisebelisoa tsa Photodetector:

Bongaka: Litšoantšo tsa X-ray, lisebelisoa tsa video tsa endoscopic.

5. Qetello le Pono ea Bokamoso

Pli-hotodiode arrays le photodetector arrays li emela mekhahlelo e 'meli ea tsoelo-pele ea theknoloji ea ho lemoha photoelectric: ea pele e ipabola ka mokhoa o bonolo le o sebetsang hantle, ha ea morao-rao e shebane le ho kopanya le bohlale. Tsoelo-pele ea tlhahiso ea li-semiconductor le bohlale ba maiketsetso e fifatsa meeli lipakeng tsa tse peli. Mohlala, moloko o latelang oa "smart" photodiode array hona joale o kenyelletsa mesebetsi ea mantlha ea ts'ebetso, ha li-photodetector arrays li ntse li tsoela pele ho lebisa tšebelisong e tlase ea matla le tharollo e phahameng.

Ha re sheba pele, ho kopana ha bona ho ka lebisa ho hlaheng ha "li-optoelectronic sensing chips" tse kopantsoeng ka botlalo, ho notlolla lits'ebetso tse ncha tsa ho khanna ka mokhoa o ikemetseng, AR / VR, le likhokahano tsa quantum. Ha u khetha lipakeng tsa mahlale ana, lintlha tse kang ho rarahana, litšenyehelo, le ts'ebetso li tlameha ho leka-lekana ho fihlela ts'ebetso e nepahetseng le katleho ea moruo.
