Zernike mixing - ?

Hi. I understand that Zernike was a physicist and that he did some work in optics, and am also aware of the Zernike Polynomials which are used in optics to describe aberrations in lenses, etc. What I do not understand is a comment that I got (from a non-native English speaker) in comparing optical materials (Si and Zr) regarding one having "Zernike Mixing" (apparently not desirable) and another not having it. What is "mixing" in "Zernike Mixing"? Does it refer to the mixing of different kinds of aberrations (polynomials) or something akin?

Zernike polynomials are used to describe aberrations in wave optics and are (sort of) interchangable with Seidel coefficients. Zernike polynomials are orthogonal on the unit circle, so I can't understand what is being 'mixed'. I have never head of the term 'Zernike mixing'.
 

What is Zernike Mixing?

Zernike Mixing is a mathematical technique used to combine two or more wavefronts or optical beams. It was developed by physicist Frits Zernike in the 1930s and is commonly used in optics and imaging applications.

How does Zernike Mixing work?

Zernike Mixing involves using mathematical operations, such as addition or multiplication, to combine the wavefronts or beams. This results in a new wavefront or beam with properties that are a combination of the original components.

What are the applications of Zernike Mixing?

Zernike Mixing is commonly used in optics and imaging applications, such as in telescopes, microscopes, and laser systems. It can also be used for wavefront correction in adaptive optics systems.

What are the advantages of using Zernike Mixing?

Zernike Mixing allows for the manipulation and combination of wavefronts and beams with precision and control, making it a valuable tool in optics and imaging. It can also be used to correct for aberrations and improve image quality.

Are there any limitations to Zernike Mixing?

While Zernike Mixing is a powerful mathematical tool, it is not a perfect solution and has its limitations. It is limited by the accuracy of the measurements used to create the wavefronts and beams, and it can also introduce noise and errors in the combined wavefront or beam.
