Project IRENE Using optical scanning to digitize ethnographic field recordings on wax cylinders

Plot of Probe Data

The image is a plot of the data measured by the probe on the scanning machine. The probe measures and reads out the height of a surface in its range at 180 points on a line 1.8mm wide. This plot results from measuring a 1.8mm line on a cylinder. The groove intersects the line several times as it winds around the cylinder and so shows up as several crescent shaped dips in the height of the surface.
