Abstract

We have previously reported on the design and operation of a novel single-chip optical correlator prototype. Two ferroelectric liquid crystal SLMs and a high-speed APS camera were built into a single CMOS integrated circuit. Diffractive Fourier transform lenses were fabricated onto the surface of a window which was mounted on top of the chip. We are now working towards implementing the correlator as a business card-sized module mounted on a PCI card which can be plugged into the motherboard of industry standard PCs. We are also upgrading the SLMs to have analog optical modulation capability. The PCI card contains input and output image buffers, plus high-speed circuitry which digitizes the four analog output channels of the correlator's camera. This paper describes the system we are developing, some of the electronic and optical engineering issues involved, and the present status of our work.
