SUMMARY

Circular polarization is a key concept in the functionality of Real 3D glasses, which utilize quarter wave plates to achieve the desired effect. Real 3D glasses consist of a linear polarizer followed by a quarter wave plate, with each eye's polarization set at 90-degree angles to enhance depth perception. When two quarter wave plates are placed together and rotated, they can alter the polarization state, affecting the viewing experience. Understanding these principles is essential for anyone working with 3D visual technologies.

I am trying to understand circular polarization and Real 3D glasses.I am sure that answers will lead to other questions.

Question 1. Are Real 3D glasses merely quarter wave plates with each eye set at 90 deg angles to the other? or..

Question 2. Do Real 3D glasses consist of a linear polarizer followed by a quarter wave plate?

Question 3. What happens when I put two quarter wave plates together, and then rotate them?
