The logical neuron is defined that its output is decided by own truth table and a combination of input logic. The logical neuron has some different characteristics in comparison with the threshold type neuron. Also, the logicneural field is defined as interconnection of the several logical neurons"2. It is interesting to investigate behavior of the logic-neural field. An optical logic-element using an array of computer-generated Fresnel holograms (Fresnel CGHs) was reported3. In the method, each logical element is driven by two coded input and generates a coded output according to same rule of input. The output of the element can be introduced to input of next elements. Therefor, there is a possibility that the logic-neural field can be realized by the optical logic-element. In this paper, the optical logic-element using an array of Fresnel CGHs is studied for one dimensional optical logic-neural field as shown in Fig. 1
