Outline

1. Introduction
   • Briefly describe Diffraction
   • Background of Talbot Effect
   • picture of talbot images
   • Background of Fresnel Zone plates
   • picture of zone plate
     in each describe concepts and introduce formulas for foci, number all equations
2. Setup
   • Describe Physical setup
     • Insert picture of mirrors and laser
     • Take picture of optical bench and carriage!!
     2 pictures of cable with and w/o laser on
3. Must make diagram!!
4. The lens
   picture of the lens
   • The Collimation process
   • Theory
   • Diagram!!
   • Hard edge on the lens
     • thought cutting off the edge of beam because not big enough
     • strength
     • quality of lens, abnormalities
     • Side view of lens used!!
5. Talbot Effect
   • Diverging Light
     Picture of Collimated and Diverging light??
     • step by step math
     • take picture of Ronchi Grating!!
     • one picture of Talbot image
     • Chart containing All data
     • Make graphs to quantify accuracy!!
   • Collimated light
   • refer to diagram
     • Explain why periodic
     • >Make chart!!
     • graph
       • explain graph
     • plot of data precision
     • goodness etc. (in report)
6. Zone plate
   • explain why diverging light did not work
   • how collimated light works--Intro??
   • step by step math
     • Explain confusion with f/3 etc
   • show progression of pictures
   • Intensity plots of pictures--Does it show increasing intensity of foci??
   • Make chart of data!!
   • Graphs!!
   • describe graphs
