Claim One:
1. A system for measuring a dimension of an object along a predetermined axis said object having a first and a second surface defining said dimensions, comprising: projecting means for projecting first and second features on said first and second surfaces respectively along a first axis; imaging means for projecting first and second features on first and second planes respectively along a second axis; said first and secnd axis being perpendicular and said object being placed at an intersection between said first and second axis, with said predetermined axis forming an acute angle with said second axis; and processing means for determining the distances between said features and corresponding reference points on said planes, and for determining said dimensions in accordance with said distances; said projecting means including a first and a second structured light source, each said sources having a light generating element, an imaging element and a projection lens for projecting a reference image from said element along said first axis and wherein the imaging element comprises a wire disposed perpendicularly with respect to said first axis wherein said first and second features are elongated dark features.
