Wavefront curvature sensing with phase error correction system is carried out using phase retrieval based on a partially-developed volume speckle field. Various wavefronts are reconstructed: planar, spherical, cylindrical, and a wavefront passing through the side of a bare optical fiber. Spurious fringe pattern in the reconstructions due to a small tilt in the plane illumination wave is detected and numerically corrected for. Difference in the curvatures of two spherical wavefronts is also evaluated. Possible applications include angular displacement and range measurements.
