sCMOS detector for imaging VNIR spectrometry

Abstract

The Optical Information Systems at the Robotics and Mechatronics Center of the German Aerospace Center (DLR) has more than 30 years experience with high-resolution imaging technology. The paper shows the institut’s scientific results of leading edge instrument and focal plane designs for EnMAP VIS/NIR spectrograph. The EnMAP project includes the technological design of the hyperspectral spaceborne instrument and the algorithms development of the classification. Kayser-Threde GmbH has the lead of the space segment and the Geo Forschungs Zentrum Potsdam is the Principal Investigator of EnMAP. The paper gives an overview over the challenging FPA design and the achieved performances including the verification program at DLR, new control possibilities for sCMOS detectors in global shutter mode and key parameters like PRNU, DSNU, MTF, SNR, Linearity, Spectral Response, Quantum Efficiency, Flatness and Radiation Tolerance will be discussed in detail.
