Abstrakt

Przedstawiono dalsze testy systemu akwizycji danych EVT4 do elektrycznej tomografii pojemnościowej. Modułowy system, który może mieć do 32 kanałów z indywidualnym przetwornikiem analogowo-cyfrowym, został zaprojektowany w celu zapewnienia małej niepewności pomiaru pojemności przy dużej prędkości obrazowania. Wydajność systemu w kontekście obrazowania 3D została zweryfikowana eksperymentalnie. W szczególności pokazujemy, że możliwy jest pomiar zmian pojemności wywoływanych niewielką zmianą rozkładu przenikalności elektrycznej dla najbardziej odległych elektrod odpowiednio zaprojektowanego czujnika 3D przy pomocy naszego systemu. Pomiary międzypłaszczyznowe wraz z pomiarami par elektrod najbardziej odległych są niezbędne do dokładnej rekonstrukcji rozkładów 3D. Ze względu na wrażliwość pomiarów pojemności uzyskanych w opracowanym urządzeniu, pomiary dla wszystkich par elektrod mogą być wykorzystane w problemie odwrotnym – układ równań może zostać rozszerzony. Chociaż współczynnik uwarunkowania numerycznego macierzy takiego układu jest wysoki, możliwa jest rekonstrukcja obrazu z wykorzystaniem danych uzyskiwanych w naszym systemie. Pokazane są wyniki rekonstrukcji obrazu 3D dla prostych obiektów testowych.
