Holography is a photographic technique that records the light scattered from an object,and presenting it in a way that appears three-dimensional (3D). This report gives a brief explanation of recording and displaying of a reflection hologram and aims to document the three different methodologies from capturing of 3D images to printing them using external holographic printer. First methodology is 3D objects generated using computer-aided design (CAD) programs such as Google Sketch to be printed as 3D Holograms, Second methodology is 3D images captured using 3D Profilometer to be printed as 3D Hologram and the Third methodology is series of images which is recorded using a webcam camera to be printed as 3D hologram.The first and second methodology’s 3D hologram is printed with the technology of Zebra Imaging using application such as SketchUp and ZScapeTM Preview. On the other hand, the third methodology’s 3D hologram is printed with the technology of General Optics Laboratory (GEOLA) using application such as i-LumoLAB. Methods to use these applications will be illustrated for better understanding. Both the process and technology of Zebra Imaging and GEOLA to print a 3D hologram will also be mentioned respectively. To further add on, the technology currently used by the University of Toronto will also be briefly mentioned. A summary for each methodology mentioned above will be shown with an aid of a flowchart, showing the resulting hologram images printed by Zebra Imaging and GEOLA.
