The input encoding algorithm of the polarization-encoded optical shadow-casting (POSC) scheme is modified to include the design of trinary combinational logic units. For illustration, the modified algorithm is deterministically employed in the design of trinary adders. Two design approaches are examined for identifying the constraints and flexibilities that are encountered depending on whether the zero-output conditions are considered. The more complicated POSC overlap equations are handled by incorporating LED source encoding to the input encoding process.
对偏振编码光投影（POSC）方案的输入编码算法进行了修改，以纳入三进制组合逻辑单元的设计。为便于说明，在三进制加法器的设计中确定性地采用了修改后的算法。研究了两种设计方法，以确定根据是否考虑零输出条件而遇到的约束和灵活性。通过将LED源编码纳入输入编码过程来处理更复杂的POSC重叠方程。
