- Abstract
The Institute of Optical Sensor Systems (OS) at the Robotics and Mechatronics Center of theGerman Aerospace Center (DLR) has more than 35 years of experience with high-resolution imagingtechnology. This paper shows the institute’s scientific results of the next generation of CMOS detectordesign in a TDI (Time Delay and Integration) architecture.This project includes the technological design offuture high or multi-spectral resolution spaceborne instruments and the possibility of higher integration. DLR OS and the Fraunhofer Institute for Microelectronic Circuits and Systems in Duisburg were drivingthe technology of new detectors for future high resolution projects and hybridisation capability in order tokeep pace with the ambitious scientific and user requirements. In combination with the engineeringresearch, the current generation of space borne sensor systems is focussingon VIS/NIR high spectralresolution to meet the requirements on earth and planetary observation systems. The combination of largeswath and high-spectral resolution with intelligent synchronization control, fast-readout ADC chains andnew focal-plane concepts open the door to new remote-sensing and smartdeep-space instruments. The paper gives an overview over the detector development and verification program at DLR on FPAlevel, new control possibilities for CMOS-TDI NG-detectors in synchronisation control mode, and keyparameters like CTE, MTF, SNR, linearity, PTC, and control effort will be discussed in detail.
