Resampling the transmission matrix in an aberration-corrected Bessel mode basis

The study of the optical transmission matrix (TM) of a sample reveals important statistics of light transport through it. The accuracy of the statistics depends strongly on the orthogonality and completeness of the basis in which the TM is measured. While conventional experimental methods suffer from sampling effects and optical aberrations, we use a basis of Bessel modes of the first kind to faithfully recover the singular values, eigenvalues and eigenmodes of light propagation through a finite thickness of air.

Automated summary

Studying the optical transmission matrix of a sample provides valuable statistics on light transport through it. By using Bessel modes of the first kind as the basis, more accurate results on the singular values, eigenvalues, and eigenmodes of light propagation can be obtained compared to conventional methods.
