In order to promote the industrialization and application of ternary optical computer,and improve the effi-ciency and stability of the existing operator unit,this paper proposes the theory,principle,and structure diagram of ternary optical logic unit(TOLU).According to decrease-radix design theory,the primitive characteristic structure is designed,and the optimization results in a simple TOLU optical path and circuit structure.With the successful production of TOLU as the core,ternary optical computer prototype system,SD16,is built.On this basis,we expound an innovative idea of the recon-figuring method for 18 kinds of ternary logic operation primitives and generating reconfigurable codes.The reconfigurable codes of compound operation primitives are analyzed,and the correlation between compound operation primitives and row calculator is established.The key technical problems of generating reconfigurable codes of any ternary logic unit are solved.The experimental results show that the construction theory and structure of the TOLU of SD16 are feasible,calcula-tion results are accurate,the operation is stable and reliable.Furthermore,the advantages of ternary optical calculator are verified that it supports multi-bits calculation,can be allocated by bit and can be reconfigurable by bit.
