摘　　要：为有效利用运算部件像素资源,在介绍了降值设计理论、三值逻辑光学运算部件结构、三值逻辑光学运算器使用像素的情况等问题之后,提出并详尽讨论了三值光学计算机数据位与光学运算部件像素之间的一种映射方法。该方法包含了"以像素位为单位"进行映射、"像素组合互补性优先"、"定时映射"等策略。采用了"定时映射等待队列"、"构造像素组合互补运算器组"等关键技术。描述了相应程序的流程,并给出了相应的实验方法,验证了该方法的可行性和有效性。In order to use components-pixels effectively, taking full consideration ofthe problems such as the decrease-radix design principle, tri-valued logic optical operating units, situation of the tri-valued logic optical operating units using LCD pixels and so on, a method for mapping from components-pixels to data-bits of ternary optical computer is put forward. The method includes a number of mapping strategies such as mapping by pixels-bit, taking complementary in components-pixels for preference, timed mapping and so on, and amount of technologies such as periodically mapping wait queue, making up complementary group of logic unit and so on. Finally, it describes the program follow, and also provides the empirical approach to verify the feasibility and effectiveness of the method.
