Reconstruction of a Three-dimensional Color-video of a Point-cloud Object using the Projection-type Holographic Display with a Holographic Optical Element

Here, we managed to reconstruct a three-dimensional color video of a point-cloud object using a projection-type holographic display with a holographic optical element as an optical screen. The holographic optical element has the function of an off-axis concave mirror and has been created by the wavefront printer digitally. We defined and implemented an algorithm to reconstruct a three-dimensional image at a chosen position considering the specification of the holographic optical element designed digitally. We successfully demonstrated to reconstruct the color video in question composed of three-dimensional images through the holographic optical element.
