Concentric intensity stripes were observed in the images of a 512*512 pixel CMOS camera chip. By measuring wavelength dependence and intensity dependence of the stripes. and analyzing the processed wafers structurally, it was concluded that the observed patterns originate from crystal defects in the bulk of the wafer underneath the epitaxial layer.
