Accuracy of surface tension measurement from drop shapes: The role of image analysis

Laplacian drop shapes and effect of random perturbations on accuracy of surface tension measurement for different drop constellations

“…Third, it was established recently that the computational parameters can be controlled: Different optimization schemes yield identical answers [43] and edge detection algorithms based on very different strategies yield the same results [53]. Therefore, the conclusion seems inevitable that errors must arise from the quality of the experimental image and the experimentation.…”

Dynamics of drops — Formation, growth, oscillation, detachment, and coalescence

“…As the technique is commonly in use, several attempts are performed to assess and to extend its capability to different experimental conditions or applications. For example, in [25] overviews on the limitation of surface tension measurements with PAT are discussed. However, most of the work is concerned with the use of the technique for equilibrium or very slow dynamic conditions.…”

Pattern search methods for pendant drops: Algorithms for rapid determination of surface tension and surfactant transport parameters

“…This step alone has warranted a detailed analysis from other researchers [7]. For this manuscript we use a pixel threshold analysis [8] to define pixels occupied by the continuous or drop phases.…”
