我们研究了非循环演化的Berry相位，利用部分缠绕光纤中的线偏振光的偏振方位角在圆柱表面上的旋转。使用围绕旋转轴的旋转规，所观察到的偏振方位角的旋转对应于由实际演化的轮廓C、赤道上的大圆和连接它们的纵线所包围的表面上的球形矩形的面积，而极规的旋转包围连接球体的天顶的球形三角形。通过从旋转规范到测地线规范的变换，将观测值转换为Berry相位。因此，我们可以确认，Berry的相位的非循环的发展是由Samuel和Bhandari提出的测地线规则。
We investigated Berry's phase for noncyclic evolution using the rotation of a polarization azimuth of linearly polarized light in a partially wound optical fiber over the surface of a cylinder. Using a rotation gauge around the rotation axis, the observed rotation of the polarization azimuth corresponds to the area of a spherical rectangle over the surface enclosed by the contour C of actual evolution, a large circle on the equator, and a longitudinal line connecting them, whereas the rotation of the polar gauge encloses a spherical triangle connecting the zenith of the sphere. The observed values were converted to Berry's phase by transformation from the rotation gauge to the geodesic gauge. Consequently, we could confirm that Berry's phase for a noncyclic evolution is given by the geodesic rule proposed by Samuel and Bhandari.
