f/f0 for a spherical bead inside of a droplet as a function of droplet shape, distance from the droplet center, and the actual and apparent bead diameters. The unparenthesized tic labels on the Bead-diameter axis are the actual bead diameters. The numbers in parentheses are the apparent bead diameters which were calculated from the actual bead diameters using equation (6) and the value of f/f0 at the center of the droplet. (A) f/f0 for a bead inside of a 3μm-diameter spherical droplet. (B) f/f0 for a bead inside of a hemispherical droplet whose base has a diameter of 4μm. For the hemispherical droplet, the bead is always positioned 1μm above the hemisphere’s base, and the distance is the horizontal distance to the symmetry axis of the droplet.
