Paper Abstract

The design and simulation results of a 64 X 64 pixels smart CMOS photodiode sensor array are presented. The chip is capable of capturing an image as well as performing real time on-chip signal processing on 3 X 3 kernel array of the image. The size of the optical system is significantly reduced by integrating the signal processing circuits on chip. It is particularly suitable for applications such as optical correlators or image processing system. The chip is designed using 0.8 micrometers standard CMOS process technology. It is incorporated with processing circuitry to implement low-pass and high-pass image filters as well as the processing algorithm required by a 1/f binary phase optical correlation system.
