Abstract

A glasses-free stereoscopic display has been developed in which a large diameter concave Stretchable Membrane Mirror (SMM) is used both as a viewing screen and optical element. SMMs offer considerable advantages over traditional imaging optics in terms of reduced weight and cost, and are revolutionary in their ability to vary their radius of curvature to give a wide range of mirror f/Nos. This is achieved by controlling the magnitude of an applied pressure difference which acts over an edge clamped metallized polyester membrane, forming the basis of a SMM. A stereoscopic display has been developed in which a 1.2-m diameter SMM is membrane, forming the basis of a SMM. A stereoscopic display has been developed in which a 1.2-m diameter SMM is used. Stereo pairs are projected at the surface of the mirror and viewed through a pari of virtual viewing windows. Such a configuration minimizes light loss, giving a very bright image against the specular reflecting surface of the SMM. The image can be formed in front/on/behind the plane of the SMM, making both real and very large sized virtual images possible. Several formats ranging form simple stereo photographs to live stereo video feed in a telepresence display have been viewed using this system.
