TL;DR: Using the lensfree video microscopy platform to perform high-throughput real-time monitoring of cell culture, this work introduces specifically devised metrics that are capable of non-invasive quantification of cell functions such as cell-substrate adhesion, cell spreading, cell division, celldivision orientation and cell death.

TL;DR: In this article, the Fractal Iterative Method (FrIM) was used for modeling the measurements obtained from laser guide stars that entail spot elongation and tip/tilt indetermination, mixed with low order measurements from natural guide stars.

TL;DR: This work proposes a regularized reconstruction method that includes several physically-grounded constraints such as bounds on transmittance values, maximum/minimum phase, spatial smoothness or the absence of any object in parts of the field of view and presents the promising results of reconstructions from experimental in-line holograms obtained in two different applications.

TL;DR: Three different algorithms based on the Fourier diffraction theorem are developed and compared to obtain fully 3D reconstructions to perform multiangle acquisitions on 3D cell cultures embedded in extracellular matrices and compare well with standard microscopy.

TL;DR: This paper includes a tutorial on how to reconstruct in-line holograms using an inverse problems approach, starting with modeling the observations, selecting regularizations and constraints, and ending with the design of a reconstruction algorithm.
