1. A three-dimensional, non-contact scanning apparatus for scanning a three-dimensional object having a longitudinal axis defined by the longest dimension of the object, comprising:
- a holder for holding the object to be scanned;
a main carriage movable linearly towards and away from said holder parallel to the longitudinal axis of the object when held thereon;
a linear actuator for linearly moving said main carriage;
a rotatable carriage rotatably mounted on said main carriage;
a rotatable drive for rotating said rotatable carriage around the longitudinal axis of the object when held on said holder;
and an optical scanner carried by said rotatable carriage to rotate therewith around said holder and the object when held thereon so as to scan the object, whereby linear movement of said main carriage moves the scanner along the length of said object when held by said holder, whereas rotation of said rotatable carriage moves the scanner around the object.

Abstract
A three-dimensional, non-contact scanning apparatus for scanning an object, particularly a foot, includes a holder for the object to be scanned, a main carriage movable linearly towards and away from the holder and the object when held thereon, a rotatable carriage rotatably mounted on the main carriage and formed with an opening for accommodating the holder and the object when held thereby, and an optical-beam scanner carried by the rotatable carriage to rotate therewith so as to scan the object by an optical beam outputted by the scanner.

11. A three-dimensional, non-contact scanning apparatus for scanning an object, comprising:
-
a holder for holding the object to be scanned; a main carriage movable linearly towards and away from the holder and the object when held thereon; a rotatable carriage rotatably mounted on said main carriage; and an optical-beam scanner carried by said rotatable carriage to rotate therewith around said holder and the object when held thereon so as to scan the object by an optical beam outputted by said scanner; said rotatable carriage including a reflector between said scanner and said object, and an oscillating drive for oscillating said reflector to oscillate said beam for a predetermined arc substantially parallel to the direction of linear movement of the main carriage. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method for the non-contact scanning of a subject'"'"'s foot with the long dimension of the foot being at a predetermined direction, comprising:
-
rotating an optical beam of a scanner around the subject'"'"'s foot while linearly displacing the scanner parallel to the long dimension of the subject'"'"'s foot to scan the front part of the subject'"'"'s foot; and then rotating the optical beam of the scanner around the subject'"'"'s foot while angularly displacing the scanner to scan the rear part and heel of the subject'"'"'s foot. - View Dependent Claims (18, 19, 20)
