  • Contact-angle measurement method, contact-angle measurement device, bioprosthetic-member inspection device, and storage medium
    Patent number: 10226202
    Abstract: This contact-angle measurement method is a contact-angle measurement method for measuring a contact angle (?) between a droplet that is supplied to a sample curved surface and the sample curved surface. This method includes an apparent contact-angle calculation step of calculating an apparent contact-angle (?) of the droplet by using a captured image of the droplet supplied to the sample curved surface and the sample curved surface; an inclination angle calculation step of calculating an inclination angle (?) of the sample curved surface at an outer periphery portion of a contact portion between the droplet and the sample curved surface by using the captured image; and a contact-angle calculation step of calculating the contact angle (?) by correcting the apparent contact angle (?), using the inclination angle (?).
