The polarization-encoded optical shadow casting (POSC) scheme is used to design a 2-digit by 2-digit trinary multiplier. Three design algorithms for identifying the appropriate source patterns, input patterns, and output mask for both serial and parallel operations are presented. The inclusion of analyzer pattern reduces the number of pixel subcells for the POSC inputs.
