Description

A novel scheme of an interferometric microscope is proposed to visualize a geometrical spin-redirection phase image that represents the local inclination of micro surface structures of an object. The observed phase depends on the state of polarization and optical constants of the object material, which enables one to distinguish the spin-redirection phase from the conventional dynamical phase. A preliminary experiment was performed, and the phase images obtained were found to be consistent with those predicted by computer simulation based on a theoretical model.
