碩士 === 國立中央大學 === 光電科學研究所 === 99 === This study focused on the construction of a human-eye optical measurement system. The data is intended for the software eye model previously developed in the research group. Once modified to match the performance of real human eyes, the model is highly potential for investigating visual performance in ordinary lighting and display conditions and under the influence of glare sources. In order to retain the information integrity in the measured images, especially the effect of intraocular scattering, a double-pass (DP) configuration was adopted. A Badal system was included for flexible manipulations in future experiments. The optical theory of DP was first analyzed to derive the modulation transfer function (MTF) of a naked human eye. Two kinds of experiments were then implemented, one with an artificial eye and the other with real human eyes. The artificial-eye experiment served as the system calibration and protocol familiarization. The human-eye experiment provided the images for computing MTFs of human eyes. The experimental results showed the same trend as the data of the young population in the literature, which verified the feasibility of this measurement system. Subjects from different age groups could be collected in future experiments. By comparing the acquired data with the results from the human-eye model, the optical parameters of the eye model could be optimized.
