Abstract: Systems, methods, and devices that generate and display a multiple view 3-D holographic image (“image”) of a 3-D real or synthetic scene are presented. A projection system captures visual information of the 3-D scene from various perspectives and generates model data to create a 3-D model of the scene. The model data is converted to holographic data, which is respectively portioned corresponding to the respective perspectives of the scene and used to generate and display respective portions of the image on respective display sections. The display sections can be separate display sections corresponding to the various perspectives, or the display sections can be on a single display that is divided into sections for the various perspectives and a 3-D adapter is employed to facilitate display of the image in the display area, wherein reflector components can be used to reflect the portions of the image to the display area.

Abstract: Systems, methods, and devices that generate and display a holographic image(s) of a 3-D real or synthetic object scene are presented. A holographic generator component (HGC) partitions a 3-D object scene into a horizontal stack of regularly spaced vertical sub-planes that are each contributed to a respective sub-line. The HGC converts the sequence of sub-lines into a collection of diffraction patterns, which are summed up and interfered with a reference beam to generate the complete hologram, which can be or can approximate a Fresnel hologram. A multi-rate filter is employed to facilitate converting sub-lines to diffraction patterns more quickly. The multi-rate filtering can be realized using convolution in the spatial domain, realized in the frequency domain using a fast Fourier transform, and/or realized in the frequency domain using a graphic processing unit.
