For multimode fiber, modified optimization goal stressing on transmission matrix diagonalization improves method self-consistency of searching propagation-invariant modes, assuming the disturbance being Zernike aberration.
This study uses granulometry analysis combined with fractal analysis to compare normal and pathological retinal OCT images. The results revealed that pathological retinae studied here had lower complexity compared to normal retinas.

To reduce the number of measurements of motionless optical scanning holography (MOSH), a two-step phase-shifting technique is proposed. The numerical simulation results show the proposed method can reconstruct the comparable distribution compared with the four-step method.

A performance comparison between three learning-based approaches for quantitative phase imaging in digital holographic microscopy is reported. We have compared the models' resulting noise level, phase discontinuities, and fitting and prediction times.

We built photonic synapse thin-film transistor (TFT) devices consisting of a-IGZO bottom with low conductivity and a-IZO top with rapid carrier transport. This device showed a very low initial post-synaptic current by achieving a full depletion at a low negative VG and improved synaptic current amplitude for memory retention.
