TL;DR: This review aims at analyzing the state of the art of microrobots imaging by critically discussing the potentialities and limitations of the techniques employed in this field and highlighting the existing challenges and perspective solutions which could be promising for future in vivo applications.

TL;DR: The presented approach is based on the employment of a second adaptive lens, located in the detection path, that enables shifting the observation plane back to the best focus position and thus creating axial scans with homogeneous axial resolution.

TL;DR: This work demonstrates a transmission of independent signals using individually shaped wavefronts employing a single segmented spatial light modulator for optical phase conjugation regarding each light signal.

TL;DR: This work shows that after an initial calibration in a forward direction, a differential phase measurement of the back-reflected light allows for tracking and compensating of bending-induced phase distortions and presents a novel in situ calibration procedure based on a programmable guide star, which requires access to only one side of the fiber.

TL;DR: This work uses photorefractive two-wave mixing for coherent amplification of the object beam in digital holographic recording and experimentally verify that the amplification process does not affect the phase of the wavefield, which allows for digital holography phase analysis after amplification.
