Patent ID: 8462433

Claim:
A multi-channel optical image fetching apparatus, comprising a first optical polarizer, said first optical polarizer processing horizontal polarization, said first optical polarizer being located at an opening of an optical channel; a second optical polarizer, said second optical polarizer processing perpendicular polarization, said second optical polarizer being located at an opening of another optical channel; an optical imaging lens set, said optical imaging lens set processing optical transformation according to a scale of a visual angle; a polarized lights splitter, said polarized lights splitter being located at an end of said optical imaging lens set, said polarized lights splitter being an optical logic switch to control output directions of a plurality of inlet lights; at least two optical birefractive polarization transformers, said optical birefractive polarization transformers being separately located between said polarized lights splitter and said first and said second optical polarizers, said optical birefractive polarization transformers processing polar transformation to said inlet lights through controlling voltage; a programmable time sequence controller, said programmable time sequence controller controlling operational times of said optical birefractive polarization transformers according to time sequence to switch images obtained from said optical channels; and an image fetching unit, said image fetching unit fetching images obtained from different visual angles to be formed on a sensing unit according to time sequence, said image fetching unit showing said images obtained from said different visual angles.
