English term or phrase: dark current
Definition from Tyco Electronics Corporation:
The thermally induced current that exists in a photodiode in the absence of incident optical power.

Example sentence(s):
  • This voltage may be as low as 10 mV or as high as 50 V and the dark currents may vary from pA to μA depending upon the junction area and the process used. Dark current is always specified at a particular value of reverse applied voltage. optoelectronics.perkinelmer.com
  • The photodiode noise in is the sum of the thermal noise (or Johnson noise) ij of a resistor which approximates the shunt resistance and the shot noise isD and isL resulting from the dark current and the photocurrent. Hamamatsu Corporation
  • Dark current is dependent on temperature. While dark current may initially be low, it will increase as the device temperature increases. tpub.com

tamna struja
Definition:
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.

Example sentence(s):
  • Za čitav opseg energije (0.2-14 MeV) tamne struje linearnog akceleratora kalibracija je proizvela dovoljne intenzitete. - Matematički fakultet, Beograd  
  • Kao najoptimalniji odnos između osetljivosti i tamne struje fotomultiplikatora odabran je radni napon od 1 kV. Struja fotomultiplikatora merena je univerzalnim mernim instrumentom DC mikrovoltmetrom Philips PM-2436/06. - Prirodno-matematički fakultet, Novi Sad
