The three-dimensional display system disclosed herein employs the varying focal properties of a vibrating mirror to cause sequentially generated image components to appear juxtaposed in space. The mirror is constructed as a circular reflective plate having substantial stiffness and resilience. The plate is weighted about its rim and is supported by a flexible support ring engaging the plate along a concentric circular locus spaced inside of the rim so as to provide a useful curvature over substantially the entire surface of the plate.
