Abstract: The design of a CCD imaging system is introduced. It can be applied to continuously monitoring the real-time status of micro-sphere in laser fusion target with a diameter of 0.1-0.3mm. By using secondary imaging carried out by the ready objective and the zoom micro-objective, combined with field lens for compressing off-axis rays and CCD sensor, a CCD scanning and imaging system which can scan and detect the field of 8.2mm′44mm is constructed with a 2-D scanning mechanism. No matter its spatial resolution or time resolution has attained the requirements for real-time monitor, and the coating efficiency for micro-sphere film is greatly improved.
