Differences Between Differences Between Fiber Optics and Light Fiber Optics and Light
GuidesGuides•Light Guide- long,
variety of different diameters, do not concentrate light as well as fiber optics
•Fiber Optics- small, thin, transmit light more efficiently, flexible

How Do They WorkHow Do They Work
• The core has a higher index of refraction than the cladding
• The light travels through the core by constant reflection from the cladding

Where did Fiber Optics Where did Fiber Optics come from?come from?
• In the late 1800’s scientist John Tyndall found using an illuminated tank, light could travel through a curved stream
• After years of experimenting, he found that light and images were able to be carried through glass rods

How We Decided on How We Decided on Fiber Optics and Light Fiber Optics and Light
GuidesGuides
• We were going to use lasers and mirrors to reflect light through a maze
• It was suggested that we do something with fiber optics
• We did research and found out about light guides
• We brainstormed ideas

What is “Light It Up”?What is “Light It Up”?
• Various fiber optics and light guides shaped with bends and curves
• Users of the exhibit shine the light in one end and see where it comes out
• Putting colored filters in front of the light changes how it looks coming out of the other end
• This exhibit shows how light travels through fiber optics and light guides

Problems We Came Problems We Came AcrossAcross
• What kind of lights are we going to use?– How powerful will they be?– How will the lights be set up?
• What diameter of the light guides are we using?
• What are the dimensions of the exhibit?• What is the cost of the materials?• Are the light guides strong enough to
carry the light?
