接触角の自動測定に関する研究

抄録

Studies on the contact angle measurement of a liquid droplet, settled on a horizontal smooth surface of the substrate, using computer graphic image processing, are reported here.
The contact angle is one of the technological measurements of adhesion wetting of liquid to solid surface, and many technical factors affect measurement. Therefore, it is important to control those factors for the sake of standardization of automatic measuring systems and its potentiality in future. In such a system, the drop shapes, affected by various measuring conditions, are classified and applied to image processing for automatic measurement.
