Abstract

The drop profile is one of the evident differences for different liquids. An image drop sensor is developed for capturing the drop profile images real-timely in various stages during the drop growth. The drop head for forming the uniform and satiated liquid drop is designed. The original profile records of pure water and 100% ethanol during their drop growth will be presented. Edge extraction methods on drop profile are discussed. Curve fitting based on third-order polynomial linear regression is used to mathematically describe the detected edge curves of the drop profile in sequential drop formation.
