Dark Current Noise Correction Method Based on Dark Pixels for LWIR QWIP Detection Systems
Applied Sciences, 2022 The long-wave infrared (LWIR) quantum-well photodetector (QWIP) operates at low temperatures, but is prone to focal plane temperature changes when imaging in complex thermal environments.

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Effective classification of Chinese tea samples in hyperspectral imaging
, 2013 Maximum likelihood and neural classifiers are two typical techniques in image classification. This paper investigates how to adapt these approaches to hyperspectral imaging for the classification of five kinds of Chinese tea samples, using visible light ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Foot Evaluation by Infrared Imaging [PDF]
Military Medicine, 2002 For better assessment of foot injury severity during basic military training, we evaluated a simple noninvasive technique: thermography. With this infrared imaging method, we determined normal foot parameters (from 30 soldiers before training), thermographic findings in different foot stress fractures (from 30 soldiers so diagnosed), and normal ...
