Qed stitching
WebIn the field of precision optics the interferometry is the most applied measurement method to test spherical and flat objects. In principle, a standard interferometer setup is limited to these surface geometries, but interferometric systems may be modified with the aid of CGH’s or the stitching technology. As a consequence aspherical shapes and even … WebJul 1, 2013 · In 2003, QED Technologies had developed a general-purpose stitching interferometer workstation (SSI) [9] that can automatically carry out high-quality subaperture stitching of flat, spherical, and mild-departure aspheric surfaces. In 2006, the QED's SSI-A TM added asphere metrology to the SSI's capabilities [10]. In 2010, with the help of the ...
