Abstract Details

2017, Master of Science (M.S.), University of Dayton, Electro-Optics.
In previous work, a sparse object has been reconstructed using digital holographic tomography by recording the holograms with an `on-axis’ system, while the object is rotated about a single axis. The recorded holograms are processed through MATLAB® using the multiplicative technique. In this work an `off-axis’ Mach-Zehnder system is used to record holograms of each side of a die, by rotating the object along the x and y axes. Then the holograms of all six sides of the die are imported and reconstructed in MATLAB® using Fresnel techniques. The depth information of each side of the die is obtained by using phase unwrapping techniques. The unwrapped depth information is then converted into an N×3 array, and then into a point cloud image. Finally, the true three-dimensional image is constructed using point cloud image processing techniques. Once the true three-dimensional image is constructed, it is exported to a Microsoft HoloLens. The true three-dimensional image is now viewable in virtual reality while still containing the depth information, which is difficult to see with current virtual reality techniques used today, along with the capability of using hand gestures for image manipulation.
