Paper Abstract

In the present paper the authors analyze detailed optics of stereoscopic display combining cylindrical lenses and embedded striped patterns, which has been proposed to reduce the contradiction between binocular parallax and focal accommodation of the eyes. The proposed system lets the viewer see an image including high frequency striped patterns through a cylindrical lens. When the viewer is shown a striped pattern through a cylindrical lens, the depth on which his/her eyes focus depends on the inclination angle of stripes, for the cylindrical lens works as a lens with different focal length depending on the orientation of lines. To control the status of accommodation correctly, it is necessary to obtain the correspondence between the inclination angle of stripes and the focusing distance. To attain this goal we make a computer simulator to calculate the 3D optical paths. The validity of the computer simulator is confirmed by physical experiments with a cylindrical lens and a camera finder to measure the focal convergence of striped lines. We also confirm that this system can induce desired focal accommodation by measuring the eyes of the viewer seeing striped patterns through a cylindrical lens.
