Figure 9
Measured (plotted symbols) and predicted (lines) speckle widths in the radial and transverse directions versus wavevector transfer. Open and closed symbols are measured radial and transverse widths, respectively. Open and solid circles are results for a 1.2 mm-thick aerogel illuminated by a 7 µm × 21 µm (H × V) beam, open and solid squares are results for a 1.2 mm-thick aerogel illuminated by a 15 µm × 31 µm beam, and open and solid triangles are results for a 2.7 mm-thick aerogel illuminated by a 6 µm × 21 µm beam. The lines are described in the text.
