Fully assembled portable IRENE field scanner which is ready for shipment to India.

An early experimental wax record on composition board, created in the 1880's by Charles Sumner Tainter, Alexander Graham Bell, and colleagues is shown here. This record, from the collection of hte Smithsonian Museum is being scanned by the 3D imaging probe inspite of signifcant warpage and crack, which would make it otherwise unplayable.

A graphical user interface for controlling the IRENE 2D disc scanner. The large image at bottom is a sample of the data taken from the disc showing high contrast renderings of a tiny region of the grooved surface.

Overall view of the 3D cylinder scanner. Cylinder, in foreground, is held on mandrel and rotated by stage (marked with circular scale). Probe enters from right and is held on linear translation stage (lower right). Laser displacement sensor scans cylinder from above (marked with yellow safety tag).
