This Demonstration shows a 2D contour plot and a choice of 3D plots: a revolution plot, a shadow plot, stereo pairs of the revolution plots, or and profiles for various orthonormal Zernike circle polynomials . In the 3D plots, you can choose different color functions to show the height distribution of the functions. Zernike polynomials are commonly used to describe wavefront aberrations in optical systems.

Details

Wavefront aberrations are very important in studying the design, fabrication, and testing of all optical systems. Zernike polynomials, named after Nobel Prize winner Frits Zernike, are often used to describe these aberrations. The density plot shows what an interferogram testing an optical system with a given Zernike polynomial wavefront error would look like. The various 3D plots give a representation of the wavefront shape. A three-dimensional image of the wavefront aberration can be seen by looking at the stereo pairs of the 3D revolution plots. All the 3D plots can be rotated and zoomed.
