Abstract

We derive the analytical expressions to demonstrate that the asymmetrical part of the wave-front aberration function may be determined with a rotational shearing interferometer. The coefficients up to the fourth order in the radial coordinate may be found. The differential rotational shearing interferometer is proposed for measurement and detection of large amounts of aberrations, such as those anticipated in testing off-axis optical systems. The number of fringes displayed across the pupil is controlled with the shearing angle; therefore, its sensitivity may be increased by decreasing the shearing angle.
