Claim Text:
1. An optical system effective to illuminate and scan an interior wall of a mesh object having an interior bore, comprising: a light source effective to illuminate said interior wall; a rigid support rod having a diameter effective to prevent collapse of said mesh object; wherein said support rod has a cross section having an optically clear viewing section that is flanked on a first and a second side by a non-transparent section; a source of linear motion, having a compliant surface to transfer motion to said mesh object, that rotates said mesh object around said support rod; an image taking lens disposed externally to said mesh object and configured to view said interior wall through said optically clear viewing section of said support rod and having a numerical aperture greater than 0.1 so that when said interior wall is in focus, an exterior wall on an opposing side of said mesh object is out of focus; and a camera optically aligned with said image taking lens and effective to scan said interior wall.
