We present a prototype integrated circuit design suitable for use as a neural backplane in an optoelectronic artificial neural network. The device consists of a 4 4 array of optical input, electronic output processing elements. The processing elements can sample the temporally multiplexed grey scale generated by a binary mode ferroelectric liquid crystal spatial light modulator. They implement...
An electronically addressed spatial light modulator is introduced. It is based on the hybrid technology of ferroelectric liquid crystal over silicon, and comprises an array of 256 256 pixels operating at a charge balanced frame rate of up to 2.1 kHz. The pixel circuit, incorporating a static random access memory latch and an exclusive-OR gate, has significant performance advantages over the single...
Liquid Crystal (LC) over silicon spatial light modulators (SLMs) have the potential to be used in miniature head mounted displays and in compact projection display systems. For this application the silicon backplane design is invariably based on a single transistor DRAM memory layout which offers the potential for very high resolution devices. However, a problem arises when these devices are incorporated...
