Abstract
Methods of recording and analyzing stereoscopic displays using chiral liquid crystal materials are presented. The methods include cameras that encode stereoscopic pictures in both the film and video formats.
Claims25
An apparatus for the recording of stereoscopic images, said images being comprised of first and second images, each having at least first and second color fields, said apparatus comprised of:
- first and second lenses, transmitting light forming the color fields of the respective first and second images, and
- polarization encoding means, wherein the light of each of said first and second color fields of each of said first and second image is polarized in one of two substantially orthogonal polarization states, wherein the polarization orientation of the light of said first color field of said first image has an orthogonal polarization orientation to the light of said first color field of said second image and the polarization orientation of the light of said second color field of said first image has an orthogonal polarization orientation to the light of said second color field of said second image, and
- an image combining means, wherein the polarization encoded light forming the color fields of said first and second images is directed to form coextensive images upon a recording target, and
- polarization analyzing means, wherein at least segments of the polarization encoded color fields of said first and second images are selectively directed to said target, and
- a recording target, wherein at least segments thereof are sensitive to the light of said color fields.
