OPTICS AND TECHNOLOGY

Analyse a technological device or procedure that was designed to make use of light and its properties.  Explain how it works and how it has benefitted society.  You will present your findings to the class in a short 5-minute presentation.  Try to evaluate the positive and negative impacts of this optical technology and make a final decision about its usefulness.

Suggested presentation outline:

 	Introduce your optical device/procedure.
 	How does it work?  What properties of light is it based on?
 	Societal impacts: both positive and negative.

Suggested topics: ( not limited to )
Technological devices related to sources of light: 
lasers, LED’s, glow sticks, fluorescent lights, phosphorescent lights

Technological devices that use the properties of light:
microscopes, solar ovens, cameras, retroreflectors, fibre optics, laser surgery (in general), binoculars, security mirrors (convenience stores)

Technological device or procedure related to human perception of light:
eye glasses, contact lenses, low light vision sensors, laser eye surgery, polarized lens sun glasses, coloured filters for dyslexia,
