| Summary: | We present the development process of a prototype CCD imaging system which is being built at Korea Astronomy Observatory(KA() for astronomical applications. The CCD imaging system requires very low noise and high stability characteristics and is widely used for astronomical purposes form infrared to ultraviolet wavelength regions. However its system design, particularly for the controller design technique, as heart of the system, is not secured in Korea so far. The prototype electronics developed in this study consists of a single chip controller which was implemented in an EPLD(Erasable Programmable Logic Device) and an analog driver, a video processor with a LN2 cooling cryostat. A PC system was employed to control the whole system and to store the image data considering compatibility of the system. We have successfully obtained the first image in the laboratory with the prototype of this imaging system, and an image of the M15 at Sobaeksan Astronomy Observatory. |
