The Spectral Analysis of Dynamic Laser Speckle Patterns Generated by Brownian Particle Suspensions: A Stroboscopic Effect Based Filtering Technique
Figure 6
The full-field power spectrum maps of for 2.08 μm particles recorded at modulation frequency of 10 Hz (a), and 400 Hz (b). The power spectrum profiles (scattered dots) measured along the horizontal reference line for 10 Hz (c), and 400 Hz (d). The solid and dashed lines are the calculated power spectrum profiles at corresponding frequencies.
