Large Array Of Cmos Image Sensors-based Imaging System To Study

With the development of CMOS Image Sensor (CIS) technology, CIS has been applied to the domain of space exploration such as cameras for remote sensing images, star trackers. The researches on commercial CIS could facilitate the R&D on the CIS imaging system, which will be of great benefit to designs on the relevant aerospace equipment.This thesis presents the history, features and the cardinal principles of CIS. The comparisons between CIS and CCD are also introduced. Then an experimental system is proposed, in which the image sensor is IBIS5-A-1300 manufactured by FillFactory NV. Based on the researches on its unique rolling shutter and synchronous shutter and the analysis of its timing diagram, the timing control is realized on the FPGA via VHDL. As of hardware design, the separation of the imaging part and the controlling part, four layers of PCB and the stable supply voltage outputted by Low Dropout regulators are applied to make this system be characteristic of high integrated quality, reliability and flexibility. Experiments show that the system works stably and has low power dissipation. The images captured by this system have good effects.At last, the thesis indicates the deficiencies in the system and how to improve its performance. This system will be a useful reference for other similar systems in this domain.
