Abstract:
An autostiginatic far field simulator comprising:A) an autostigmatic cube defining an image plane and comprising: 1) a beam splitter, 2) a pinhole, 3) an optic defining a reference sphere having, by reason of said beam splitter, two optical centers of curvature; that are, a first optical center of curvature at said image plane and a second optical center of curvature at said pinhole, B) an adjustable objective mirror having by reason of said beam splitter, a first focus and a second focus and positioning elements for positioning said objective mirror such that said first focus of said objective mirror is located at said first optical center of curvature and said second focus is located at said second optical center of curvature, and C) an imaging objective for relaying a magnified image of said image plane to a view plane for viewing interference fringes.
