Traditional conic-based models rely on conic constants, which exhibit high interindividual variability and limited age correlation, hindering population-level modeling. This study introduces a modified Poisson-Gauss (moPG) model, an enhance...

Quantitative phase imaging enables label-free visualization of transparent and weakly absorbing cells with the transport of intensity equation, derived from the paraxial wave equation widely used for its simple and non-interferometric appro...

It was established by Green and Wolf in 1953 that an electromagnetic wave can be characterized by a complex scalar potential, including its energy and momentum densities. In this paper, we show that, for electromagnetic beams, this scalar p...
Interferences in degree of coherence and polarization with partially coherent light beams [0.03%]

We theoretically propose an experimental scheme to observe the interference effect in the degree of coherence and polarization. With the fact that the phase difference can be significantly affected by the low coherence length, we predict th...

We present a solution to the problem of branch points in wavefront sensing by circumventing the problem altogether and reconstructing the full complex optical field instead of the phase. Traditional wavefront reconstruction algorithms are b...
Minimal equivalent Abbe number under the constraint of lens surface shapes for hyperchromatic doublet lenses [0.03%]

The minimum equivalent Abbe number can be used to describe the maximum axial dispersion achievable by a hyperchromatic doublet lens. In this study, the axial dispersion limit of such a doublet is investigated under the constraints of lens s...
Method of field expansions for multiply layered media with quasiperiodic interfaces [0.03%]

Periodic structures are foundational in applied optics; however, more permissive forms of periodicity are becoming increasingly important in electromagnetics. Due to both their central importance and the high cost of their production at the...
Bandwidth-optimized regularization for low-frequency recovery in quantitative phase imaging [0.03%]
带宽优化正则化在定量相位成像中低频恢复中的应用

We propose the expanded matrix solution of the transport of intensity equation (EMS-TIE), introducing a tunable parameter (th) to the Tikhonov regularization term. This design addresses the limitation of conventional Tikhonov solvers, where...
Moiré effect without a multi-line grid preserving the phase of a physical image fragment containing a single line [0.03%]
无需多线网格且保持物理图像单线片段相位的莫尔效应

To observe the moiré phenomenon, two grids are required. Nevertheless, the effect can be achieved without a physical grid, using computer-generated grids based on a fragment of the image. This approach allows for the observation of the moi...
Investigation of laser propagation characteristics based on a warm-air convection turbulence simulator [0.03%]

Free-space light propagation is inevitably influenced by atmospheric turbulence, which leads to scintillation, arrival-of-angle (AOA) fluctuation, or even optical link interruption. Conducting outfield experiments directly often involves ha...
