Rotational shearing interferometer. In the rotational shearing interferometer, one pupil image is rotated by a small angle about the optical axis with respect to its replica (reference beam). The two images will overlap if the center of the pupil is coincided with the rotation axis where the rotation of one wavefront with respect to the other.

In the rotational shearing interferometer, one pupil image is rotated by a small angle about the optical axis with respect to its replica (reference beam). The two images will overlap if the center of the pupil is coincided with the rotation axis where the rotation of one wavefront with respect to the other. Holograms of incoherent objects can be recorded with a rotation-shearing interferometer allowing corrections of wavefront errors. Holographic images taken in our laboratory, either through aberrated optics or atmospheric turbulence, have been successfully freiheit-yildiz.com by: 4. Multiwavelength shearing interferometry for measuring the slopes, curvatures, and shapes of thin films/substrate systems Changxing Zhang,1,2 Xuelin Dong,1,2,3 Xue Feng,1,2,* and Keh-Chih Hwang1,2 1AML, Department of Engineering Mechanics, Tsinghua University, Beijing , China 2Center for Mechanics and Materials, Tsinghua University, Beijing , China. implementation in a rotational-shearing interferometer Ivan Moreno, Gonzalo Paez, and Marija Strojnik An analytical expression is derived for the tilt introduced into a wave front by a Dove prism with. We have utilized the rotational symmetry of a perfect target to improve defect detection sensitivity by using rotational‐shearing interferometry.
