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.
July 10th 2001
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.
