dc.description.abstractUp to this day, many types of 3D displays have been developed. However, there remain some challenges in the displays, for example, restriction of view points and vergence-accommodation conflict. A 3D display was proposed in the past using light diffusion within 3-dimensionally positioned micro voids processed in a crystal glass cuboid. It is able to present 3D objects to any number of simultaneous viewers at any viewpoint, without wearing any kind of special glass-like equipments. However, in order to successfully present 3D objects, the projection must be adjusted precisely for each individual micro void by investigating the correspondence between each projector pixel and micro voids. This process not only requires a great amount of user's effort but also consumes a lot of time. Hence, for this research, pixel-to-void matching methods which can automatically find out correspondence between each projector pixel and micro voids by using a camera were developed. These methods were verified in the experimental systems to be able to perform such matching procedure automatically and accurately. In addition, using multiple projectors, brightness and resolution of the display was improved. Two types of the displays were developed, one aimed to improve especially its brightness and the other aimed to improve especially its resolution. While the latter one resulted in higher resolution but in subjective evaluation experiment no improvement of visibilities was verified, the former one resulted in higher brightness and it was verified to have improved visibilities in subjective evaluation experiment.
