Imaginary Looking Glass

Author: Judee Shipman
Topics: High School, Physics

Grade Level: 9th - 12th; Type: Holography

Objective:

Demonstrate and explain holographic technology.

The goals of this project are:

  1. To find out if a holographic image of a magnifier still magnifies.
  2. To illustrate and explain the effect.

Research Questions:

  • What is a hologram?
  • How do holograms work?
  • Does a holographic image of a magnifying glass still magnify?

Holographic images have captured our collective fascination since the early 1960s. They are used for purposes like security, data storage and artwork. It is said that if you make a holographic image of a magnifying glass, the image alone will still provide a magnified view of the object beneath it. In this project you will discover the truth behind the claim.

Materials:

  • Computer with Internet access
  • Color printer
  • Digital camera
  • Typical office/hobby/hardware/craft supplies (paper, poster board, glue, etc.).

Experimental Procedure:

  1. Read overview of relevant topics (see bibliography below)
  2. Address all of the terms and research questions mentioned here.
  3. Search and print out interesting images relevant to your topic.
  4. Visit holographic image galleries and view the works.
  5. Contact holography experts for info and advice.
  6. Find out if a hologram of a magnifying glass still magnifies. Explain why or why not.
  7. Write your findings in a detailed report.
  8. Include photos, diagrams and demonstrations in your science fair display.

Terms/Concepts: Diffraction; Interference; Volumetric Display
