A PC based CCD emulation system

Abstract

A novel method of electrically emulating an area array charge coupled device (CCD) using a personal computer is described in this paper. A dual port memory is used to simulate the photosensitive area of the CCD. Suitable clocks are also generated as is done in the actual CCD system.

The CCD emulation system is useful for the development of any hardware and software which interfaces with a CCD. This system is used to test the on-board micro-processor used in the Indian Remote Sensing (IRS-1C) satellite.
