Abstract
Abstract Apparatus for use in autostereography for moving the objective lens of a camera and the camera back transverse to a subject along parallel linear paths between extreme positions. The apparatus includes a linkage for moving the lens and back relative to one another during exposure, the back being moved more rapidly than the lens so that the distance traveled by the back between the extreme positions thereof is greater than the distance traveled by the lens. Another linkage is included for pivoting the back about an axis perpendicular to the direction of linear motion and parallel with the plane of a photosensitive element mounted in the back. The back is pivoted through a predetermined angle with respect to the lens during movement of the lens and back between their extreme positions. The spacing between the lens and back is variable for focusing, and the linkages automatically vary the relative movement of the lens and back in inverse relation to the space therebetween while maintaining constant the angle through which the back is pivoted relative to the lens during movement of the lens and back between their extreme positions.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
188 words
Autostereographic apparatus comprising, in combination: a first carriage; support means mounted for pivotal movement on said first carriage for supporting a graticule and an associated photosensitive element; a second carriage including means for mounting an objective lens in position to transmit light toward a graticule and photosensitive element supported on said first carriage; means mounting said carriages for linear motion along parallel paths substantially perpendicular to the pivotal axis of said support means and the optic axis of a lens supported on said second carriage; a first linkage coupled between said carriages for moving one of said carriages along said path thereof between two extreme positions thereof in the same direction as the other of said carriages and relative to said other carriage in response to and simultaneously with movement of said other carriage between extreme positions thereof; said first linkage including means for causing said second carriage to move relative to said means mounting said carriages, at a slower rate than said first carriage; and a second linkage coupled with said support means for pivoting the latter during and in response to movement of said first carriage.
Claim 2
Dependent Claim
188 words
Autostereographic apparatus comprising, in combination: a first carriage; support means mounted for pivotal movement on said first carriage for supporting a graticule and an associated photosensitive element; a second carriage including means for mounting an objective lens in position to transmit light toward a graticule and photosensitive element supported on said first carriage; means mounting said carriages for linear motion along parallel paths substantially perpendicular to the pivotal axis of said support means and the optic axis of a lens supported on said second carriage; a first linkage coupled between said carriages for moving one of said carriages along said path thereof between two extreme positions thereof in the same direction as the other of said carriages and relative to said other carriage in response to and simultaneously with movement of said other carriage between extreme positions thereof; said first linkage including means for causing said second carriage to move relative to said means mounting said carriages, at a slower rate than said first carriage; and a second linkage coupled with said support means for pivoting the latter during and in response to movement of said first carriage.
