Astrometric errors introduced by interpixel capacitive coupling in hybridized arrays

Baum, Stefi; Ninkov, Zoran; Donlon, Kevan

Interpixel capacitance (IPC) between adjacent pixels in hybridized arrays gives rise to an electrostatic cross talk. This cross talk causes MTF degradation and blurring of images or spectra collected using these devices. As pixel size is driven down from the 18-µm pixel pitch of the H2RG read out circuits to the 10- or 15-µm H4RGs IPC …
