- DARK CURRENT: (Prúd za tmy) termicky indukovaný prúd, ktorý existuje vo foto-dióde pri absencii optického napojenia. Abasys - by Michal Zugec
- Example sentence(s)
- Prúd ID sa nazýva prúd za tmy a je totožný so záverným prúdom neosvetlenej fotodiódy. Je jednou z charakteristických veličín fotodiódy a platí o ňom všetko to, čo sme povedali o závernom prúde polovodičových diód. - Elektronika by Michal Zugec
- V princípe je mechanizmus transportu rovnaký pre nosiče náboja generované termoemisiou (prúd za tmy) ako aj pre fotogenerované nosiče (fotoprúd). Aby sa zvýšil pomer medzi fotoprúdom a prúdom za tmy na akceptovateľnú úroveň, ktorá je porovnateľná s ostatnými typmi detektorov, je vhodné znížiť teplotu aktívnej oblasti chladením [5]. - Slovenská Technická Univerzita by Michal Zugec
- Stredná kvadratická hodnota šumu prúdu za tmy
d d i2 = 2eBI (2)
kde e je náboj elektrónu , Id je prúd za tmy a B je šírka frekvenčného pásma. - TUKE by Michal Zugec

- Definition(s)
- Το θερμικό ρεύμα που διαρρέει μια φωτοδίοδο απουσία φωτός, ονομάζεται "ρεύμα σκότους". Συχνά χρησιμοποιείται ο γενικότερος όρος "υπόστρωμα". Own research - by Anna Spanoudaki-Thurm
- Example sentence(s)
- Στην ανάστροφη πόλωση της διόδου και όταν υπάρχει απόλυτο σκοτάδι κυκλοφορεί ένα πολύ μικρό ρεύμα μέσα από την δίοδο το οποίο ονομάζεται ρεύμα σκότους. Το ρεύμα αυτό είναι της τάξεως των μΑ και όσο αυξάνεται η ένταση του φωτός στην δίοδο, έχουμε γραμμική αύξηση του ρεύματος, η οποία εξαρτάται από το μήκος κύματος του φωτός καθώς και από την ένταση της φωτεινής ροής πάνω στην δίοδο. - Ραδιοερασιτεχνική λέ� by Anna Spanoudaki-Thurm

- Definition(s)
- Tamna struja se može definisati kao nepoželjno naelektrisanje koje se prikuplja u CCD pikse-lima usled prirodnih termalnih procesa koji se pojavljuju dok uređaj radi na bilo kojoj temperaturi iznad apsolutne nule. Na bilo kojoj temperaturi parovi elektrona i šupljina slučajno se stvaraju i rekombinuju u silicijumu i na granici silicijuma i silicijum dioksida. U zavisnosti od toga gde su stvoreni, neki od tih elektrona će se prikupiti u CCD izvorima i lažno prikazati kao naelektrisanja signala na izlazu. Velike tamne struje ograničavaju korisnu upotrebu uređaja, jer je proces stvaranja slučajan, pa tamna struja doprinosi šumu. CET čitalište - by Mira Stepanovic

- Corrente di natura termica in un fotodiodo in assenza di illuminazione. Nozioni elementari di fotometria - by Roberto Crivello
- Example sentence(s)
- La piccola corrente che attraversa il fotodiodo in assenza di illuminazione.
Diventa importante solo quando si usa il diodo in polarizzazione inversa - Nozioni elementari di fotometria by Roberto Crivello
- In assenza di luce, la corrente di buio di un fotodiodo corrisponde alla corrente di saturazione inversa dovuta ai portatori minoritari generati termicamente. - Manuale di elettronica e telecomunicazio by Roberto Crivello
- Poiché il dispositivo fotorivelatore è polarizzato inversamente, anche in completa assenza di potenza ottica incidente, nel circuito esterno scorre una piccola corrente di conduzione inversa Id, detta corrente di buio (Dark Current), di cui si deve tenere conto in fase di progetto di rivelatori per segnali ottici con fotorivelatori a semiconduttore - Rivelatori di segnali ottici by Roberto Crivello
