Optical implementation of parallel fuzzy logic using a single electron trapping device

An optical system using a single electron trapping (ET) device with area-en coding of input fuzzy variables and negations is proposed to perform fuzzy logic operations in parallel. In our scheme, each encoding cell is only com posed of one encoding cell so that the resultant is still the image in whic h there is no space between any two pixel rows. Based on the storage and er asure characteristics of the ET device, all of the fuzzy logical functions of two images can be implemented in parallel and spatial-invariant by progr amming the illumination form of data arrays. No thresholding device, lens a rray and decoding mask is needed, therefore, our system exhibit a high oper ation speed and large information throughout. The system can be compact. Th e experimental results are also given.
