论文摘要
中红外（IR）阵列探测器已用于空间中的天文观测。但是，尚未详细研究其光谱响应曲线的均匀性，对哪些曲线的理解对于使用大型阵列格式的光谱观测很重要。我们使用傅立叶变换红外光谱仪和低温光学器件来表征IR阵列检测器中所有像素的光谱响应，以高信噪比测量。我们测量了Si的光谱响应：作为杂质带传导（IBC）阵列，这是Akari/IRC的飞行备用检测器。结果，我们发现si：由于阵列沿阵列的行和列方向的光谱响应中具有内在变化。我们还发现Si的截止波长：IBC阵列取决于入射光的强度。
Mid-infrared (IR) array detectors have been used for astronomical observations in space. However, the uniformities of their spectral response curves have not been investigated in detail, the understanding of which is important for spectroscopic observations using large array formats. We characterize the spectral responses of all the pixels in IR array detectors using a Fourier transform infrared spectrometer and cryogenic optics for measurements at high signal-to-noise ratios. We measured the spectral responses of the Si:As impurity band conduction (IBC) array, a flight back-up detector for AKARI/IRC. As a result, we find that the Si:As array has intrinsic variations in the spectral response along the row and column directions of the array. We also find that the cutoff wavelength of the Si:As IBC array depends on the intensity of the incident light.
