Here a transport model is used to simulate amplitude-only imaging and intensity-based quantitative phase imaging in a turbid medium. We derive an optical transfer function for propagation through a scattering medium. We also show that, as expected, scattering leads to a degradation in the spatial resolution in both forms of imaging, while the magnitude of the phase retrieved using a solution of the transport-of-intensity equation decreases as the optical density of the scattering medium increases.
