Abstract
We proposed novel screen systems for magnifying stereographic depth lengths, such as a flat screen, a spherical dome screen and an oval dome (horn-type) screen as well as theoretical mechanisms for magnifying depth length. We fabricated the screens and confirmed the correspondence of theoretical and experimental values. The magnification ratio of the oval dome screen to the flat screen increased from 1 to 6.93 as the screen curvature parameter b increased from 1 to 4. Furthermore, we achieved depth distortions and obtained their eliminations.
