Abstract

Optical parallel logic device using twisted nematic liquid crystal cells doped with dichroic dyes and dichroic filters are proposed. Operation of this device is expressed by combination of transfer functions of simple 2X2 matrices. This device can perform several logic operations simultaneously by different wavelength and/or polarized lights. An iterative system can also be composed by using this device and template matching is examined by this system.
