Based On Cmos Image Sensor Imaging Systems For The Surface Array Lupa4000 Study

With the development and perfect of CMOS imaging technology. CMOS image sensor has been appled broad because of its characteristic of low-cost, simple digital interface and fast-speed, especially in the domain of space exploration such as cameras for remote sensing images, star trackers. The thesis research on CMOS image sensor produces by Cypress Corporation and aims to achieve the method of its driving circuit;and it could facilitate the R&D on the CMOS image sensor, which will be of great benefit to designs on the relevant aerospace equipment.This thesis does some research on contents below: Firstly, it presents the history, features and the primary principles of CMOS image sensor. The comparisons between CMOS and CCD are also introduced. Then the structure, principle and performance of LUPA4000 prodeced by Cypress was describled. An experimental system is proposed, in which the image sensor is LUPA4000 manufactured by Cypress Corporation. Based on the researches on its synchronous shutter and the analysis of its timing diagram, the timing control is realized on the CPLD 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.
