Optical testing using the transport-of-intensity equation
Optics Express, 2007 The transport-of-intensity equation links the intensity and phase of an optical source to the longitudinal variation of its intensity in the presence of Fresnel diffraction. This equation can be used to provide a simple, accurate spatial-phase measurement for optical testing of flat surfaces. The properties of this approach are derived.

Radiative Heat Transfer and Effective Transport Coefficients [PDF]
, 2010 The theory of heat transfer by electromagnetic radiation is based on the radiative transfer equation (RTE) for the radiation intensity, or equivalently on the Boltzmann transport equation (BTE) for the photon distribution. We focus in this review article,

A Fourier-based Solving Approach for the Transport of Intensity Equation without Typical Restrictions [PDF]
, 2018 The Transport-of-Intensity equation (TIE) has been proven as a standard approach for phase retrieval. Some high efficiency solving methods for the TIE, extensively used in many works, are based on a Fourier-Transform (FT).

Optical dispersions through intracellular inhomogeneities
Physical Review Research, 2023 The transport of intensity equation (TIE) exhibits a noninterferometric correlation between the intensity and phase variations of intermediate fields (e.g., light and electrons) in biological imaging. Previous TIE formulations have generally assumed free-
