WIPO Patent Application WO/2015/064363

Kind Code:

A1

Abstract:

This invention measures a contact angle on a sample curved surface more accurately. This contact-angle measurement method is used to measure the contact angle (γ) between a sample curved surface (104) and a liquid droplet (2) supplied thereto. Said method includes the following steps: an apparent-contact-angle computation step in which an apparent contact angle (α) for the liquid droplet (2) is computed using a captured image of the sample curved surface (104) and the liquid droplet (2) supplied thereto; an inclination-angle computation step in which the captured image is used to compute the inclination angle (β) of the sample curved surface (104) at the outside edge (2a) of the contact area between the sample curved surface (104) and the liquid droplet (2); and a contact-angle computation step in which said inclination angle (β) is used to correct the abovementioned apparent contact angle (α) so as to compute the abovementioned contact angle (γ).
