Document Type and Number:
Japanese Patent JP6178211
Kind Code:
B2
Abstract:
The present invention aims to more precisely measure the contact angle of a sample curved surface. This contact-angle measurement method is a contact-angle measurement method for measuring a contact angle (³) between a droplet (2) that is supplied to a sample curved surface (104) and the sample curved surface (104). This method includes an apparent contact-angle calculation step of calculating an apparent contact-angle (±) of the droplet (2) by using a captured image of the droplet (2) supplied to the sample curved surface (104) and the sample curved surface (104); an inclination angle calculation step of calculating an inclination angle (²) of the sample curved surface (104) at an outer periphery portion (2a) of a contact portion between the droplet (2) and the sample curved surface (104) by using the captured image; and a contact-angle calculation step of calculating the contact angle (³) by correcting the apparent contact angle (±), using the inclination angle (²).
