本文描述了使用校正透镜的立体3-D显示系统的检查。该系统的目的是通过简单的技术来减少观看立体3-D图像时的调节和会聚差。该校正透镜是单焦点透镜，并且添加到偏振滤光镜。在这项研究中，作者进行了三个实验，以检查适当的使用条件和效果的校正透镜。在实验1中，在调节距离和会聚距离理论上相等的六个条件下检查校正透镜的屈光力。在实验2中，通过测量在观看沿深度方向移动的视觉目标期间的折射，检查适合于校正透镜的立体3-D图像的呈现条件。在实验3中，通过使用实验1和2中获得的使用条件来检查校正透镜的有效性。根据实验结果，得出以下结论。(1)矫正镜片改变调节距离。(2)使用具有适当屈光力的校正透镜并设置呈现立体3-D图像的适当条件，减少了调节和会聚之间的差异。(3)矫正透镜的使用影响了视疲劳的主观症状。
This paper describes an examination of a stereoscopic 3-D display system using a correction lens. The purpose of the system is to reduce the accommodation and convergence difference during viewing stereoscopic 3-D images by using simple technique. This correction lens is a mono-focal lens, and added to the polarized filter glasses. In this study, the authors carried out three experiments in order to examine the appropriate utilization conditions and effects of the correction lens. In experiment 1, the refractive power of correction lens was examined under six conditions in which distances of accommodation and convergence were theoretically equal. In experiment 2, the presenting condition of stereoscopic 3-D images suitable for the correction lens was examined by measurement of refractions during viewing visual target that moved in depth direction. In experiment 3, the effectiveness of the correction lens was examined by using the utilization conditions obtained in experiment 1 and 2. From the results of the experiments, the following conclusions were drawn. (1) Correction lenses shift the accommodation distance. (2) Using a correction lens with the appropriate refractive power and setting the appropriate conditions for presenting stereoscopic 3-D images reduced the difference between accommodation and convergence. (3) The use of a correction lens affected the subjective symptoms of asthenopia.
