Better 3D Inspection with Structured Illumination Part I: Signal Formation and Precision

, 2015
For quality control in the factory, 3D-metrology faces increasing demands for high precision and for more space-bandwidth-speed-product SBSP (number of 3D-points/sec). As a potential solution, we will discuss Structured-Illumination Microscopy (SIM).

Sub‐Unit‐Cell Logic Governs Transport in TPMS Architectures

Advanced Science, EarlyView.
ABSTRACT Next‐generation energy, thermal, and chemical systems require architectures capable of highly efficient transport across multiple length scales. Triply periodic minimal surfaces (TPMS), first conceptualized in 1865, offer inherently scalable geometries with exceptional transport potential, yet mechanistic links between topology and performance

Photonuclear Population of 229m,gTh in Th‐Doped Crystals Toward Nuclear Clock Development

Advanced Science, EarlyView.
This study demonstrates a novel photonuclear approach for producing the nuclear clock isomer 229mTh in thorium‐doped crystals, overcoming current supply limitations. Through cross‐section calculations and Monte Carlo simulations, we identify optimal crystal materials and irradiation conditions, achieving high signal‐to‐noise ratios.

Three-dimensional optical metrology and models for non-contact diffuse optical tomography of small animals

SPIE Proceedings, 2007
We introduce a novel approach for calibrating an axis of rotation in a 3D optical metrology system. The system uses a stereo camera pair, along with rotation and translation stages for obtaining a 3D model of the surface of small animals. The metrology system will be part of a fully non-contact diffuse optical tomography (DOT) scanner for small animal ...

Entropy‐Guided Convolutional Neural Network Classification of Sensor Signals for Real‐Time Surface Quality Monitoring in Direct Laser Interference Patterning

Advanced Intelligent Systems, EarlyView.
Neural‐network pipeline for real‐time DLIP surface‐quality monitoring: spectral entropy of WLI topographies is used to generate interpretable K‐means labels, which are transferred to time‐resolved photodiode traces. A compact dual‐input 1D‐CNN (signal + laser parameters) learns discriminative spatiotemporal features and predicts “OK/NOK” surface ...
