This paper discusses multi-view technology for a projection-type stereoscopic display. The multi-focal screen of this display employs the diffractive function of a Holographic Optical Element (HOE). For three dimensional (3D) displays to be viewable without special glasses, multi-view is very important and this requirement is difficult to meet because the wide viewing area conflicts with the separation of viewing area between the right and left eyes. Holography is suitable for developing such an optical device. The display is a recursive multi-view stereoscopic display that uses multiple mirrored focal point HOEs. The advantage of this display is that it doesn't require mixing of stereoscopic images. The configuration is very simple because of the type of projection. The stereoscopic images from two cameras can be directly observed without editing them. The display lets more than one observer view the same 3D image at the same time.
