【Abstract】 A fast algorithm for quantitative determination of minute spatial displacement field is discussed. First, fringes observed with orthogonal slit aperture is used to determine two components of object displacement transverse to the observation direction. Then the projection transformation is used to calculate spatial displacement. The projection matrix, operational formula, FOETEAN program and experimental results show that this algorithm is convenient and valid for dealing with minute displacement and deformation of complex objects.更多还原
