Paper Abstract

Simple geometries of holographic interorometers are discussed, which secure that the influence of measuring errors on the displacement vector is very small. The design of the inferometers for the zero-order-fringe and the fringe-counting-method is characterized by 360°/n-symmetry in the position of the observation points or the scanning lines over the hologram, respectively, where n means the number of equations in the evaluation system. Very simple relations are given for the calculation of the condition number and the standard deviations of the displacement components taking into account overdetermined systcms.
