Dynamic Laser Speckle Imaging [PDF]

, 2019
ABSTRACT Utilizing a high-speed camera and recording back-scattered laser light at more than 20,000 frames per second, we introduce the first wide-field dynamic laser speckle imaging (DLSI) in which we are able to quantify the laser speckleintensity temporal auto-correlation function g

Characteristics of blood flow measurements using laser speckle imaging [PDF]

, 2006
P(論文)Three types of blood flow measurement methods using laser irradiation such as laser-Doppler flowmetry, laser-Doppler imaging, and laser speckle imaging have been utilized for measuring the peripheral blood flow because of the benefits of low ...

Confocal laser speckle time-autocorrelation imaging with adaptive orientation spatial windows

Journal of Innovative Optical Health Sciences
Conventional laser speckle contrast imaging (LSCI) suffers from static scattering and limited quantitative accuracy. To overcome these issues, we previously developed confocal laser speckle contrast imaging (CLSCI) and confocal laser speckle ...

Peripheral Neutrophil Activation and Extracellular Trap Formation in Amyotrophic Lateral Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
Markers of neutrophil activation are increased in plasma during ALS, and markers of NET formation associate with ALS survival. ABSTRACT Objectives Peripheral neutrophil levels in amyotrophic lateral sclerosis (ALS) inversely correlate with survival, suggesting a role for neutrophils in disease progression.

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

Advanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.
