The use of subaperture stitching in increasing the capability of an interferometer is discussed. Parts that would require large transmission spheres can be tested on a stitching system at higher resolution. Advances in the development of algorithms allow system calibration to be an integral part of a stitching system. This enables calibration of lateral errors as well as accurate determination of magnification and distortion.
