Block-Based Mode Decomposition in Few-Mode Fibers

Block-Based Mode Decomposition in Few-Mode Fibers

A block-based mode decomposition (BMD) algorithm is proposed in this paper, which reduces computational complexity and enhances noise resistance. The BMD uses randomly selected sample blocks of the beam images to restore mode coefficients instead of all pixels in the beam images. It allows for block...
