Summary: Conventional lens imaging systems use lenses to focus incident rays, while a lensless imaging system uses a mask to project the rays. Lensless systems are thin, lightweight, and inexpensive, but they require specific decoding algorithms for the heavily overlapped images. We propose a decoding algorithm called Fourier-ADMM to rapidly unwrap the overlapped images and suppress diffraction from tiny holes. Based on this algorithm, a lensless imaging system is proposed, achieving super-resolution and providing users with additional options for robust, high-resolution, fast decoding without complicated calibration.

Summary: This paper presents a Multi-resolution Data Fusion algorithm that accurately interpolates low-resolution electron microscope data. The algorithm utilizes small amounts of unpaired high-resolution data to train a neural network denoiser and incorporates a Multi-Agent Consensus Equilibrium problem formulation to balance the denoiser with a forward model agent for fidelity to measured data.

Summary: This work presents a super-resolution acoustic imaging method that can invert the distribution, strength, and structure of sources in three-dimensional space. By utilizing the nonlinear coupling process between a low-frequency sound field and a high-frequency plane wave, this method overcomes the resolution limit. The reconstructed results with different source strengths and frequencies demonstrate the effectiveness of the proposed method, particularly for low-frequency source imaging. This method enhances the super-resolution analysis capability of acoustic imaging tests and provides deeper physical insights into various propulsion systems in underwater and aerospace systems.

Summary: This paper presents a super-resolution computed tomography imaging spectrometry (SRCTIS) technique by integrating the information obtained by a conventional CTIS system and a regular RGB camera, which improves the reconstruction accuracy and spatial resolution of CTIS. The unique information provided by the zero-order diffraction of the target scene is used for filtering to preserve edges and reduce artifacts. The multispectral image recovered is then mapped onto the RGB image and the spectral information is propagated to enhance the spectral resolution, achieving high spatial and spectral resolutions.

Summary: The research investigated the effect of the thickness of cesium lead halide perovskite CsPbBr3 nanoplatelets on their electronic structure and optical properties. It was found that as the thickness decreases, the bandgap increases and the band mixing becomes more significant, influencing the transition matrix element. Experimental and theoretical calculations showed that with an increase in injected carrier density, the maximum optical gain of thicker nanoplatelets saturates faster than thinner ones.

Summary: Strong light-matter interaction in 2D materials at the few-exciton level, characterized by fast coherent energy exchange between photons and excitons, is important for fundamental studies and quantum optical applications. This study demonstrates a strongly coupled gold dimer antenna with a sub-10 nm gap on a monolayer tungsten disulphide (WS2), showing a way to increase the number of excitons up to tenfold by varying the spatial mode overlap between the plasmonic field and the 2D material, with further tuning possible via plasmon-induced heating effects. These results represent progress towards quantum optical applications operating at room temperatures.

Summary: Engineering the spectral lineshape of plasmonic modes through various electromagnetic couplings and mode interferences can significantly improve plasmonic sensing. A new approach is proposed to overcome the trade-off between bulk and surface sensitivities by combining near-field and far-field coupling in an intercalated 3-disk plasmonic crystal, achieving higher figure of merit and surface sensitivity. The design simplicity and high figure of merit highlight the potential of the 3-disk structure for a robust plasmonic sensing platform.
