Optical Magic Lenses

We altered a standard polarization-based passive stereo projection setup and employed a standard LCD panel as a purely optical, tangible magic lens device. Due to the properties of polarized light, the modified passive stereo setup can be used to separate two views - a primary and a secondary layer - of the projected data. A non-powered LCD panel serves as magic lens filter, as it rotates the direction of polarized light 90 degrees, providing the user a different view on the projected data. The system is arbitrarily scalable for multiple users and can be applied to numerous applications.
