1. PolarizedLight “Polarized Light and 3D TV’s” College of Optical Sciences University of Arizona Funfest 2012

2. “What is Polarized Light?” - The direction that the light wave oscillates - Randomly(Unpolarized) - In a line(Linearly Polarized) - In a circle(Circularly Polarized)

3. Funfest 2012 “How Do You Measure Polarized Light?” -Use a linear polarizer. -Look through it and rotate it: - Unpolarized Light: NO CHANGE - Linearly Polarized Light:B  D  B  D

4. Funfest 2012 Circularly Polarized Light: “Left-Hand” CCW Light A Left-Hand Circular filter transmits this light No change in intensity as you rotate it “Right-Hand” CW Light A Right-Hand Circular filter transmits this light No change in intensity as you rotate it

5. Funfest 2012 “How Do 3D TV’s and Movies Work?” Record using 2 cameras: - one for the “right eye” - one for the “left eye” Reference Play back both the “right eye” and the “left eye” images simultaneously…

7. Funfest 2012 “So how does it work?”
