Polarized 3D Glasses

PIRA: 6H10.40

Overview:

For 3-D movies, two slightly different images are projected onto the screen simultaneously, each polarized in a different direction (e.g., one with vertically polarized light for the left eye, and the other with horizontally polarized light for the right eye, or more commonly, using circular polarization for a less restrictive viewing experience). The 3-D glasses have lenses with corresponding polarizing filters, so each eye only receives the image intended for it. Your brain then combines these two distinct, two-dimensional images, creating the illusion of depth and a single, three-dimensional scene, much like how your brain naturally combines the slightly different views from your two eyes to perceive depth in the real world.

Materials:

These glasses can be used with the polarized tape demo. Two pairs of glass can be used to show polarization.

Setup:

Set two pairs of glasses on the demo table facing each other.

How to:

They should be slightly misaligned to show the polarization of the lenses. One pair can be picked up and rotated to demonstrate the polarization of the lenses.

Safety:

There are no safety issues with this demo.
