Patent ID: 8593731

Claim:
A system comprising: a pair of sets of optical components mounted to focus a pair of images, which when viewed simultaneously by a viewer form a three dimensional image; the pair of sets of optical components including at least a first set of optical components forming a first image of the pair of images; a second set of optical components forming a second image of the pair of images, the second set of optical components being a different set than the first set of optical components, each optical component in the second set of optical components has a corresponding optical component in the first set of optical components that have the same optical properties, wherein the first optical components of the first and second sets constitute a pair of corresponding optical components; a first adjustable mounting upon which a first of the pair of corresponding optical components is mounted; the first adjustable mounting is configured such that adjusting the first adjustable mounting displaces the first image in a first direction; a second adjustable mounting upon which a second of the pair of corresponding components is mounted; and the second adjustable mounting is configured such that adjusting the second adjustable mounting displaces the second image in a second direction that is perpendicular to the first direction.
