Project Information

Computer Generated Holograms


Information About This Project

I only started to compile and create this project recently. Roughly, the idea behind it is to create a computer generated hologram by using a program that transforms an image. When a laser printer prints a copy of that transformation on transparency paper, the interference pattern from laser shown through it will recreate the image as a hologram.

Papers Found

To start my project I have chosen 5 papers to work from. The first is from another line of endeavor. "Optical Properties of dye molecules as a function of the surrounding dielectric medium" by G. Lamouche, P. Lavallard, and T. Gacoin, was featured in the June 1999 issue of Physical Review A, which was volume 59, issue 6. In my current project, the crux of my project is based on the paper, "Holography without photography" by Thad G. Walker, featured in Volume 67, and Issue number 9 of the American Journal of Physics, describing a computer program to convert images into computer generated holograms. Another paper, from Volume 40 and Issue 17 of Applied Optics, was "Computer Generated Holograms of three dimensional realistic objects recorded without wave interference" by Youzhi Li, David Abookasis, and Joseph Rosen showed a different approach to this method of holography. Another two papers were "Decomposition storage of information based on computer generated hologram interference and its application in optical image encryption" by Yongkang Guo, Qizhong Huang. Jinglei Du, and Yixiao Zhang, and "Three Dimensional source reconstruction with a scanned pinhole camera" by Daniel L. Marks, and David J. Brady, were from Applied Optics, Volume 40, Issue 17, and Optics Letters, Volume 24, Issue 11, respectively.

About Me

I am Noah Corwin. This September I will be entering the tenth grade at Syosset High School. Currently, I am participating in the Stony Brook Summer Research Institute. During my ninth grade school year I did a project where a dielectric coolant was tested to see if it could cool a computer and increase its efficiency when pumped over a microprocessor.

After several days of problems, I have finnaly gotten the small program to work. It converted an image of four black dots on a white background into the pattern I needed. Hopefully,it will work. Currently, I will be looking over both images, mainly for irregularities which would make either unusable for this project.
