摘要
A measurement method for measuring a phase corresponding to a position of an object plane by a photographed image obtained by photographing a lattice image of an object plane by a camera. A first step of projecting a grid image to convert one pitch of the grid of the grid image to be an integer pixel; The phase corresponding to the position of the surface is measured.
