Paper Abstract

In this talk, we will present the applications of inverse scattering principles with digital holography. First, I will present the recently developed 3-D holotomography setup using a dynamic mirror device, which is an optical analogous to X-ray computed tomography. In particular, I will discuss the visualization of 3D refractive index distributions of biological cells and tissues measured with the 3-D holotomography using the transfer function method. For a weakly scattering sample, such as biological cells and tissues, a three-dimensional refractive index tomogram of the sample can be reconstructed with the inverse scattering principle from multiple measurements of two-dimensional holograms. The outcome demonstrates outstanding visualization of 3D refractive index maps of live. In addition, we also discuss the application of inverse scattering principle for highly scattering layers. With wavefront shaping techniques using digital holography, we demonstrate ultra-high-definition dynamic holographic display exploiting large space-bandwidth in volume speckle. Exploiting light scattering in diffusers, we also demonstrate the holographic image sensor which does not require the use of a reference beam .
