Phase-shift calibration errors in interferometers with spherical Fizeau cavities.
Phase-demodulation algorithms in interferometry often depend on a sequence of evenly spaced reference phase shifts. These phase shifts must be accurately calibrated and can be distorted by geometric effects, especially when spherical components with high curvature are tested. Here the resulting measurement errors are quantified through mathematical analysis, and it is shown that modern phase-es...

متن کاملErrors in estimating spherical harmonic coefficients from partially sampled GCM output
This study describes a method of calculating the mean squared error (MSE) incurred when estimating the spherical harmonic coefficients of a climatological field that is sampled at a small network of points. The method can also be applied to the coefficients of any other set of orthonormal basis functions that are defined on the sphere. It, therefore, provides a formalism that can be applied in ...
متن کاملGeneral Analytic Correction for Probe-Position Errors in Spherical Near-Field Measurements
A general theoretical procedure is presented to remove known probe-position errors in spherical near-field data to obtain highly accurate far fields. We represent the measured data as a Taylor series in terms of the displacement errors and the ideal spectrum of the antenna. This representation is then assumed to be an actual near field on a regularly spaced error-free spherical grid. The ideal ...
متن کاملAre Nanoparticles Spherical or Quasi-Spherical?
The geometry of quasi-spherical nanoparticles is investigated. The combination of SEM imaging and electrochemical nano-impact experiments is demonstrated to allow sizing and characterization of the geometry of single silver nanoparticles.
