Abstract : The performance and function of the human eye are reviewed. A sensing array system devised by using the concept of the involuntary human eye motion is considered. The system's receptor-array is reduced to a moderate size by the introduction of the perturbation effect, thus decreasing the system's complexity and cost, while retaining equivalent or better system resolutions. Also, the serious lead problem of the receptor-array and the complicated, huge, mechanical scanning device are eliminated. Applications of the array systems to metrology photogrammetry are discussed. A one-dimensional experimental sensing array is built and tested. The experimental results show that the system can detect the relative position of an object-image of accuracy better than 0.001 in. Suggestions are made to the extension of the idea in the future. (Author)
