Aproksymacja czasowych zależności ładunku ciemnego w matrycy CCD

Approximation of exposure time dependencies of dark charge in CCD). In the article a new approximation method for exposure time dependencies of dark current in CCD was presented. As it was reported before, some pixels had nonlinear dark current characteristics with a significant drop of dark charge generation. The novel approximation is based on the fact that the dark current generation ratio depends on the amount of already collected charge. The method was examined on dark current dependencies of Kodak KAI-11000M CCD sensor. Slowa kluczowe: matryca CCD, prąd ciemny, korekcja obrazow, astrofotografia
