This study introduces a novel tomographic method to determine optical properties in highly scattering media using acousto-optic measurements. The technique reconstructs material properties by solving an inverse problem for light diffusion.

Area of Science:

  • Biomedical Optics
  • Photonics
  • Applied Physics

Background:

  • Characterizing highly scattering media is crucial for applications like medical imaging and material science.
  • Traditional methods often struggle with complex scattering environments.
  • Acousto-optic measurements offer a promising, non-invasive approach.

Purpose of the Study:

  • To develop a tomographic method for reconstructing optical properties of highly scattering media.
  • To utilize incoherent acousto-optic measurements for improved characterization.
  • To address limitations of existing techniques in complex scattering environments.

Main Methods:

  • A tomographic reconstruction approach based on solving an inverse problem for the diffusion equation.
  • Leveraging the principle of interior control using external wave fields.
