Patent number: 11940268Abstract: The present disclosure discloses a contact angle measuring device, including a light source, a container, a photodetector, a bubble generating unit, and a processing unit. The container includes a first and a second side walls that are opposite. The first side wall is made of a light-transmitting material, the container is filled with a liquid with light transmission inside. The monochromatic light emitted by the light source passes through the first side wall and enters an interface between the first side wall and the liquid. The bubble generating unit is configured for generating a bubble that is in contact with an inner surface of the first side wall. The photodetector is configured for detecting light intensity distribution of the monochromatic light through the liquid.Type: GrantFiled: May 6, 2022Date of Patent: March 26, 2024Assignees: Xiamen University of Technology, Riccino (Xiamen) Optical Inc.Inventors: Dong Sun, Luming Song, Xianjian Zhou, Hongyi Lin, Hong Liu, Wenzhang Zhu, Haijun Lin
