2. Holography 1948: Dennis Gabor – proposes lensless imaging: wavefront reconstruction. Calls it “total recording” or Holo gram Concept: record and recreate wavefront incident on “film”. –Amplitude & Phase How is that different than photography? How is it accomplished? –Inclusion of a reference wave, record the interference, capture the phase.

23. Interesting Aspects of Hologram Hologram is like a window. What happens if I break a hologram? What happens if I shrink / stretch a hologram?

26. Applications of Holography What does a Hologram do? How can we leverage this? Do we really know which is the reference and which is the object?

27. Microscopy

28. Interferometry – Multiple Exposure Holography What if we expose a holographic recording media multiple times? What would this reconstruct?

29. One Idea: What if we record only 2 holograms with extremely short and bright exposures? –Hologram #1 is just a diffuse background illumination. –Hologram #2 is captures a speeding bullet mid-flight. What happens when we re-create simultaneous background and bullet images?

30. Another Idea: Real time
