Annular subaperture stitching interferometric technology can test large-aperture
and the PV and RMS of residual error of the full aperture phase distribution is 0.027 and 0.0023
high numerical aperture aspheric surfaces with high resolution
the relative error of PV and RMS is -0.53% and -0.31%
respectively. The results conclude that this splicing model and algorithm are accurate and feasible. So it provides another quantitive measurement for test aspheric surfaces especially for large aperture aspheres besides null-compensation.
low cost and high efficiency without auxiliary null optics. In this paper
the basic principle and theory of the stitching method are introduced
the reasonable mathematical model and effective splicing algorithm are established based on simultaneous least-squares method and Zernike polynomial fitting. The translation errors are eliminated from each subaperture through the synthetical optimization stitching mode
it keeps the error from transmitting and accumulating. The numerical simulations have been carried on by this method. As results
the surface map of the full aperture after stitching is consistent to the input surface map
the difference of PV error and RMS error between them is -0.0074 and -0.00052 ( is 632.8nm)
respectively
