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

mörkerström


Definition from own experience or research:
Den termiskt inducerade ström som genereras i en fotodiod utan den träffas av något ljus.

Example sentence(s):
  • Detta görs för att minska ner mörkerströmmen, dvs den utsignal som erhålls när detektorn inte träffas av ljus. Mörkerströmmen beror på att den termiska rörelsen i katodmaterialet kan orsaka emission av elektroner. - KTH

Vielen Dank!

Vielen Dank, da es sich um ein Zubehörteil beim Dentalröntgen handelt, bin ich aber nicht sicher, ob Abutment passt.

Doris Wolf Kopfstütze für Zahnlose ist wahrscheinlich richtig, die Frage ist nur, weshalb Zahnlose eine andere Kopfstütze brauchen:)

ibz Das ist eine gute Frage :-)

Doris Wolf Ich konnte die Frage inzwischen klären: Der Kiefer des bezahnten Patienten wird fixiert, indem der Patient auf das Aufbissstück beißt. Da der unbezahnte Patient diese Möglichkeit nicht hat, braucht er eine andere Art Fixierung.

ibz Aha! Dann aber eher eine Kopffixierung als eine Kopfstütze, nicht wahr?


Votes in favor of/against selecting this as the best translation of the term asked
Yes  Nils Andersson: Just. (KTH, åxå)
4 hrs

Yes  Andreas Andersson: Jovisst, så heter det. Men det behöver ju inte absolut vara för en fotodiod, QWIP-detektorer och fotomultiplikatorer har också mörkerström. (Bara som några exempel jag kom att tänka på just nu. Det måste finnas massor fler.)
