چکیده انگلیسی
The readout noise of a H2RG HgCdTe NIR detector from Teledyne is measured at a temperature T=110Â K. It is shown that a Fowler mode with n=240 allows to reach a noise of 2.63e (single read). A description of the power spectrum in terms of three parameters reproduces the variation of the noise as a function the number of Fowler samples as well as its dependence on the periodicity of the sampling. The variance of the noise decreases with frequency with an effective power of 0.62 in our measurement domain. The behaviour of the detector under different experimental conditions can then be predicted.
