Optical design for several three-dimensional (3-D) displays based on floating real image formation using optical imaging elements, such as a concave mirror and a micro-mirror array device, are described. A volumetric 3-D image consisting voxels distributed in the air can be generated by moving a floating image with an optical scanner and modulating the image at a high-speed frame rate. In addition, floating multi-view autostereoscopic displays implemented by using a high-frame-rate projector and an optical scanner are described. It is possible to expand the viewing area to 360 degrees around a floating image.
