Design and evaluation of a biocular system

In this study, a biocular system is established and a biocular analysis method is proposed by analyzing the biocular parallax principle to determine the relationship between convergence, dipvergence, azimuth, and elevation. Based on the biocular analysis method, a looped optimization method for reducing biocular parallax is presented. After optimizing the biocular system, convergence of the system is between −6 mrad–6 mrad, and dipvergence is between −1.5 mrad–1.5 mrad. This satisfies the requirements of the human eye for observation with a biocular system. Experimental results are approximately consistent with theoretical analysis. This proves the accuracy of the proposed biocular analysis method.
