A new moire deflectometer setup with a built-in telescope is proposed. This setup is equally suitable for measuring both phase objects and specular surfaces requiring only minor adjustments. The telescope-based design enables high-sensitivity testing of large optical components with a 2.54-cm (1-in.) aperture optical system.
