Spherical Coordinates

13.5K
Spherical coordinate systems are preferred over Cartesian, polar, or cylindrical coordinates for systems with spherical symmetry. For example, to describe the surface of a sphere, Cartesian coordinates require all three coordinates. On the other hand, the spherical coordinate system requires only one parameter: the sphere's radius. As a result, the complicated mathematical calculations become simple. Spherical coordinates are used in science and engineering applications like electric and...

Area of Science:

  • Optics and Photonics
  • Metrology
  • Interferometry

Background:

  • Subaperture stitching interferometry (SSI) is crucial for measuring large optical surfaces.
  • The previous Subaperture Stitching and Localization (SASL) algorithm required 3D Cartesian coordinates.
  • Standard spherical interferometers output phase data directly, not Cartesian coordinates.

Purpose of the Study:

  • To develop an iterative algorithm for spherical subaperture stitching tests.
  • To process data directly from spherical interferometers, avoiding coordinate conversion.
  • To improve the accuracy and applicability of subaperture stitching techniques.

Main Methods:

  • An iterative algorithm based on the SASL algorithm was developed.
  • The algorithm directly utilizes phase difference data from spherical interferometers.
  • Unknown radii of best-fit spheres were incorporated as optimization variables.

Main Results:

  • The new algorithm successfully processes spherical interferometer data.
  • It overcomes the Cartesian coordinate limitation of the original SASL algorithm.
  • The method inherits the advantages of the SASL algorithm while adapting to spherical measurements.

Conclusions:

  • The proposed iterative algorithm is effective for spherical subaperture stitching.
  • This advancement enables direct use of spherical interferometer data in stitching tests.
  • The algorithm offers a more practical and accurate approach for large optic metrology.
