Abstract

Most of stereoscopic displays requiring no special spectacles are expensive and complex. In this paper, we propose a new stereoscopic display, composing simply at low cost. It consists of a half-mirror, two prism sheets, two fresnel convergent lenses, and two 2D-displays. This prism sheet has blind surface in one side of prisms, which has the property of absorbing light. This system divides the parallax images of right and left using the critical angle and blind surface of prism sheets. To evaluate the performance of this proposed display, we actually made a prototype display. As a result of doing some experiments, the fundamental effectiveness of this stereoscopic display was confirmed.
