Imaging of particles with 3D full parallax mode with two-color digital off-axis holography

A novel microfluidic method to simultaneously measure droplet size and interfacial tension without visualization

“…19 Currently available methods for determining droplet size include experimental measurements and theoretical predictions. To our knowledge, most droplet size measurement strategies are based on optical methods, for example, optical brightfield microscopy, 20,21 digital holography, 22 single-particle light-scattering, 23 laser interference imaging, 24 and laser particle size determination. 25 Optical brightfield microscopy can be applied in microfluidics devices because transparent materials are commonly used.…”
