Abstract

We demonstrate a method to solve the main problem involved in lattice design for subaperture stitching interferometry. That is calculation of the aspheric departure of a subaperture whose location is given arbitrarily. The simulated measurement data with unknown phase values are transformed into the global model frame, which satisfy the nominal surface equation. Then the phase values can be solved and used to calculate the aspheric departure with piston, tilts, and power removed. Accordingly, the subaperture lattice is determined with preferred interferometer parameters.
