Abstract
A displacement detection method detects a displacement from phase singularities before and after the displacement, by specifying the phase singularities based on predetermined elements by acquiring the elements from a phase structure of the phase singularities, and detecting positions of the phase singularities after the displacement based on the elements acquired by specifying of the phase singularity.
