Linear polarization is a technique used in 3D stereo display that separates stereo frames. This technique uses polarizer overlays that polarize the left and right frames differently. This method was first introduced in 2011 and is also known as “passive 3D.”
To view the 3D content, viewers need to wear polarized glasses that filter the frames for each eye. The glasses used in this technique do not have any electronic or processing capabilities.
The linear polarization technique was the first 3D technology used in big motion pictures, including the 1953 horror film “House of Wax.” In this technique, the theatre projector projected stereo frames that were 90 degrees apart. Later, this technology adopted a clockwise/counterclockwise direction similar to the RealD technique used today.
Overall, linear polarization is a key technique used in 3D technology that delivers a unique and engaging viewing experience.
What is linear polarisation in 3D technology used for?
Linear polarisation is used to separate stereo frames to create a 3D viewing experience. It is achieved using polarizer overlays and polarised glasses.
What is the difference between linear polarisation and other 3D technologies?
Linear polarisation uses a passive technique with polarizer overlays and glasses, while other technologies like active 3D use electronics in the glasses to create the 3D effect.
Is linear polarisation used widely in 3D movies and TVs today?
The use of linear polarisation has decreased in recent years, with other techniques becoming more popular due to technological advances.
Linear polarization is a fascinating technique used in 3D technology that delivers a unique viewing experience. Although it has decreased in popularity over the years, it remains a critical component of the early development of 3D technology and an exciting area of study for researchers.
