H2RG（2K × 2K）近红外探测器Fowler（n）采样噪声的频率分析
Frequency Analysis of the noise in the Fowler(n) sampling of a H2RG(2Kx2K) Near-IR Detector
摘要：
在温度T=110K下测量了Teledyne公司的H2RG HgCdTe近红外探测器的读出噪声。它示出，具有n = 240的福勒模式允许达到2.63e的噪声（单读）。在3个参数方面的功率谱的描述再现了噪声的变化作为福勒样本的数量的函数，以及其依赖于采样的周期性。噪声的方差随频率降低，在我们的测量域中有效功率为0.62。在不同的实验条件下的检测器的行为，然后可以预测。
英文摘要：
The readout noise of a H2RG HgCdTe NIR detector from Teledyne is measured at a temperature T=110K. 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 3 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.
