Figure 2
Series of scattering patterns of a feather shaft wall section, recorded with the beam perpendicular to the shaft axis (vertical), along the scan line represented in Fig. 1. From left to right and then top to bottom, the positions starting from the outer face to the inner face of the shaft correspond to the following depths in micrometres: 5, 25, 28, 30, 35, 60, 70, 78, 82, 90, 100, 110, 112, 114, 118, 145, 175, 195, 215 and 235. The intensity grey scale is linear. |
