“…The phase retrieval of DH is also of great importance in flow diagnostics, which is capable of resolving the phase shift and refractive index variation caused by the changes of pressure, temperature, density, chemical species concentration, etc. For example, Evans et al applied digital phase-sensitive holography to acquire the phase of the shock-wave which helps to remove the phase distortion from the image [183]. Wu et al proposed three models of DIH for the in situ characterization of burning composite fuel particles, which has been demonstrated in distinguishing the dispersed fuel particle and the weakly scattering gas flame using both amplitude and phase information [167].…”

In various multiphase flows, the characterization of particle dynamics is of great significance to understand the interaction between particles and the surrounding flows. Digital holography (DH) is a versatile 3D imaging technique, which has shown great advantages in quantitative analysis and non-intrusive diagnosis of various particle fields. This review focuses on the advances and applications of DH in multiphase reactive/non-reactive flows in the last two decades. The basic principles of DH are introduced firstly, including its mathematical background and representative experimental configurations. Then, the image processing algorithms for hologram reconstruction and automatic focusing are summarized, along with the methods for separating overlapping particles and tracking moving particles. As a prevailing and powerful tool, the recent applications of deep learning in processing holographic images is also included in this review. Furthermore, the applications of DH in the characterization of particle dynamics in multiphase reactive/non-reactive flows are surveyed in detail. Lastly, the review concludes with the discussion of the technical limits of DH and provides insights into its promising future research directions.
