Game Plan

Divergent Light

  • calculate Talbot images
    • use both big and small Ronchi gratings
    • measure by moving either lens or camera
  • measure zone plate foci
    • use both zone plates
    • measure by moving either lens or camera

    Collimated Light

  • foci of both zone plates
    • move either plate or camera
      • apply thin lens formula
  • Talbot images...cyclic?
