Outline of Final Research Achievements

The purpose of this research is the development of a display technique for three-dimensional image formation viewable from a surrounding area based on auto-stereoscopic display by integral imaging, imaging in the air with a concave mirror, and 360-degree scanning with a rotating mirror. There are problems in formed images, such as image distortion caused by optical aberration, and image deficiency caused by inappropriate light direction propagating from each point of the image. We analyzed the property of image formation by measuring projected images on a screen placed at several positions in the optical system, and comparing the results with that of optical simulation. In addition, we measured the shape of the concave mirror in order to apply the data to optical simulation for precise optical design. We formed three-dimensional aerial image that can be viewed from a surrounding area, and confirmed the validity of the proposed method.
