We present a new layout providing different magnifications and resolution capabilities in lensless imaging by using an electrically tunable lens (ETL). Experimental validation is reported using a resolution test target and prostate cancer cells.

We propose learning tomography plus (LT+) which outperforms learning tomography (LT) for reconstruction of 3D refractive index distributions of highly scattering samples. We validate the performance of LT+ using experimental data as well as simulations.

We develop a phase retrieval algorithm that utilizes the hybrid-input-output (HIO) algorithm with a deep neural network (DNN). The DNN architecture, which is trained to remove the artifacts of HIO, is used iteratively with HIO to improve the reconstructions. The results demonstrate the effectiveness of the approach with little additional cost.

The scintillation index of the I0-Bessel-correlated beams generated as temporally incoherent superposition of Laguerre-Gaussian modes with different coherence states and different values of the Orbital Angular Momentum (OAM) index on propagation in atmospheric turbulence is reported. The scintillation index is shown to decrease with the increase in the OAM index.
