Abstract
We evaluate the general wavefront function of an optical system that does not possess a rotational symmetry, subject to the infinitesimal rotational shear. The interference pattern of an astigmatic wavefront generated in the differential rotationally shearing interferometer is equal to that in the Twyman-Green interferometer, but rotated by 45 degrees. The interferometric pattern of the 45 degree astigmatism changes into that of the 90 degree astigmatism. The interference pattern of a comatic wavefront generated in the differential rotationally shearing interferometer is equal to that in the Twyman-Green interferometer, but rotated by 90 degrees. The coma along the x-axis changes to the coma along the y-axis.
