Development Of 4kx4k Long-Range Digital Imaging System

The high resolution and large image area of long-range digital imaging system is designed by using a KAF-16803 area CCD. The long-range digital imaging system can avoid the radiation to the operator. The imaging system consists of the clock sequencer generation unit, the CCD drive circuits unit of clock sequencer, the video signal processing unit, high-speed data optical fiber transmission unit, high-speed data acquisition unit and software. The performance of this system are as the following: 4kx4k; 100% fill factor; 16bit A/D; exposure time flexibility adjusted range from 5 mu s to 5s; single module optical fiber transmission, 40km; These features make the long-range digital imaging system for applications in Astronomy, Industrial, Security and life sciences fields.
