| Research Abstract |
Ellipsometry is widely utilized for investigating surface and optical properties of thin films. We proposed a new concept for 3D shape measurement of specular objects by ellipsometry. For precise and fast measurement, imaging ellipsometer using a liquid crystal variable retarder was developed. A high precision achieved by our proposed method is expected for 3D shape measurement in various applications.
