Point-spread function engineering enhances digital Fourier microscopy

摘要

While numerous optical methods exist to probe the dynamics of biological orcomplex fluid samples, in recent years digital Fourier microscopy techniques,like differential dynamic microscopy, have emerged as ways to efficientlycombine elements of imaging and scattering methods. Here, we demonstrate,through experiments and simulations, how point-spread function engineering canbe used to extend the reach of differential dynamic microscopy.
