Abstract
For precise panchromatic and hyperspctral imaging, it is essential to model the transfer function of complete imaging system. The modeling mandates accurate determination of, EO parameters of detector array, optical system transfer function and their dependence on thermal and vibration variations. This paper presents the methodology and experimental setup for characterization of the EO parameters for SATURN SWIR integrated detector array and Dewar cooler assembly (IDDCA) to determine the charge to voltage function (CVF), linearity, readout noise, dark current, non-uniformity, array operability and Full well capacity (FWC), electrical dynamic range (DR). The presented method uses the photo-detector linear signal model to generate a photon transfer curve (PTC) which is further used to calculate the SWIR detector EO parameters.
