Paper Abstract

Principal component analysis is applied to the calculation of the power α of the 1/fα dependence of the power spectrum density of a sequence of frames affected by a 1/f noise and obtained from a focal plane array. This method provides an operational alternative of characterization of this type of noise that has been successfully applied to simulated and experimental data. The α parameter obtained by this method corresponds with a global characterization of the whole array. Besides, a calibration lifetime is calculated. This temporal parameter indicates when the 1/f noise begins to be more noticeable than the temporal noise in the images of the array.
