Here are a few examples...

This first image shows a dual projector setup, using polarizing filters working in conjunction with polarized glasses to provide the separate left and right eye images. This is one of the most simple techniques, and provides a very good image if set-up and managed well.

This following image shows an lcd based monitor system that uses two polarized screens and a 'pepper's ghost' reflection screen to provide a 50/50 mix between the two polarized images.

While the following image shows a single screen LCD monitor where each alternate image line is polarized differently, allowing for viewing of the stereo image without the need for two screen, but at the cost of reduced resolution.

All the above systems require glasses to see the Stereoscopic image.

Yet another monitor system uses a Lenticular approach, which doesn't require glasses, but is vastly reduced in resolution, and reminds us of the old 3D image cards you used to get for free in your Wheatybangs!

We are still waiting for a truly usable, no-glasses, Stereoscopic viewing system...
