英文摘要	We present a method for extracting the zero-gravity surface figure of a mirror. If the structures and constraints of the mirror and its support mounts are invariable during measurement, we can use an algorithm to extract its zero-gravity surface figure by measured data obtained through three different orientations of the mirror. These orientations can be user-defined within the proposed rules, thereby reducing measuring constraints. The proposed algorithm is also available for the gravity-reversing method. To devise this algorithm, we propose and prove a nonlinear superposition property that the mirror system's displacement of nodes at any gravity-included angle is equal to the sum of the projection of the displacement of nodes at θ = 0 and θ = π / 2. This method is verified through comparisons with a series of numerical stimulations. © 2019 Society of Photo-Optical Instrumentation Engineers (SPIE).
