Article Abstract

Backscattering Mueller matrix polarimetry has recently received wide attention in biomedical and clinical applications. However, during practical measurements, pixel saturation can inevitably arise from the specular reflection process, leading to inaccurate tissue information acquisition. In this Letter, we systematically analyze the influence of pixel saturation on backscattering Mueller matrix polarimetry. It is theoretically and experimentally found that coupling schemes and saturation thresholds of polarization channels influence Mueller matrix imaging. Meanwhile, the saturation area inversely correlates with incident angles. Based on the analysis, we propose an image fusion optimization strategy to recover accurate polarization properties from saturated Mueller matrix images. This study provides a reference for addressing saturation challenges in computational Mueller matrix polarimetry for biomedical studies and clinical applications.

As semiconductor manufacturing advances into the angstrom-scale era characterized by three-dimensional integration, conventional metrology technologies face fundamental limitations regarding accuracy, speed, and non-destructiveness. Although optical spectroscopy has emerged as a prominent research focus, its application in complex manufacturing scenarios continues to confront significant technical barriers. This review establishes three concrete objectives: To categorize AI-optical spectroscopy integration paradigms spanning forward surrogate modeling, inverse prediction, physics-informed neural networks (PINNs), and multi-level architectures; to benchmark their efficacy against critical industrial metrology challenges including tool-to-tool (T2T) matching and high-aspect-ratio (HAR) structure characterization; and to identify unresolved bottlenecks for guiding next-generation intelligent semiconductor metrology.

Significance: Bacterial biofilm agglomerates are the cause of hard-to-treat implant-associated infections but currently can only be distinguished using sophisticated microbiological or molecular biological methods. Optical methods can potentially provide a label-free, noncontact approach to detect the presence of bacterial species associated with implant infections that could aid in the early diagnosis of implant-associated diseases.

Aim: Our aim is to measure the polarization signal from implant-associated bacteria biofilms using Mueller matrix polarimetry.

We report a Mueller matrix ellipsometer design using dual continuously rotating anisotropic meta wave plates, which determines the full set of Mueller matrix elements in the terahertz spectral range. The instrument operates in the frequency domain and employs a frequency tunable, solid state synthesizer based, continuous wave terahertz source with sub-MHz bandwidth. The implemented source permits operation within 82-125 and 170-250 GHz, without and with an additional frequency doubler, respectively.

Purpose: The aim of this exploratory randomized controlled clinical trial was to compare profilometric and radiographic changes following early implant placement in sites treated with alveolar ridge preservation versus spontaneous healing (SH). Additionally, the study aimed to investigate clinical parameters of the implants up to 3 years following crown insertion.

Methods: Thirty-five patients exhibiting either intact buccal bone plates or buccal dehiscence of up to 50% after single-tooth extraction of incisors, canines, or premolars were enrolled.
