abstract = "The effects of the misalignment of a test surface in a deflectometry system were explored. A Stewart Platform Hexapod stage was used to create the intentional misalignment, rotate the test surface position around the X and Y axes as well as displace their Z location. The measured surface maps were analyzed in coefficients of a fit of the surface map to the Zernike coefficients. The Zernike term results were adopted to show the relationship between the induced pose changes and the reconstructed surface map. Such an understanding of the errors in location and orientation and deflectometry measurement results would be beneficial in the future measurement of ophthalmic optics with a deflectometry system.",
