摘要 | A wide-area fundus camera used for screening the retinae of infants was designed. In this paper, the design methods of the device's illuminating and imaging systems were investigated. Based on James Polans' wide-field human eye model and a set of ophthalmic anatomy data, an infant eye model was established. Then, a tapered fiber scheme was proposed for wide area illumination. Finally, the design method of a wide-area fundus camera imaging system, including the contact lens and relay lens, is introduced. The design example shows that the Field Of View (FOV) of the wide-area fundus camera can reach 130, and the object resolution of the fundus can reach 10 m. The design results meet the national standards YY0634-2008 for fundus imaging equipment and meet the requirements for infant retina screening. Copyright 2020 Chinese Optics. All rights reserved. |
