We present sequential three-dimensional images captured during the process with a confocal scanning laser microscope. Characteristic lengths parallel and perpendicular to the electric field were obtained from the spatial correlation functions of the images. It was found that the droplet growth rate increased with both the electric field and the volume fraction of droplets. A function describing the droplet growth rate was derived from theory using the "hierarchical model" and was found to be in good agreement with the experimental results.American Physical SocietyJournal Articleapplication/pdfhttp://hdl.handle.net/2115/44032https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/44032/1/PRE82-3_031805.pdf1539-3755Physical Review E8230318052010-09enginfo:pmid/21230099info:doi/10.1103/PhysRevE.82.031805©2010 The American Physical Societypublisher
