Development of a beam propagation method to simulate the point spread function degradation in scattering media [PDF]
, 2019 Scattering is one of the main issues that limit the imaging depth in deep tissue optical imaging. To characterize the role of scattering, we have developed a forward model based on the beam propagation method and established the link between the ...
