Figure 5
Speckle visibility contrast as a function of temperature for 72 nm-radius latex in glycerol; the data shown were collected at a wavevector transfer of Q = 0.1 ± 0.01 nm−1. Blue circles: 2 ms exposure; red squares: 5 ms exposure; black diamonds: 10 ms exposure. The 2 ms data are multiplied by a factor of 1.039 to account for the reduced contrast resulting from the shutter transit time. Solid lines are theoretical predictions based on Brownian motion. |
