Photoacoustic Imaging in Oxygen Detection [PDF]

Applied Sciences, 2017
Oxygen level, including blood oxygen saturation (sO2) and tissue oxygen partial pressure (pO2), are crucial physiological parameters in life science. This paper reviews the importance of these two parameters and the detection methods for them, focusing on the application of photoacoustic imaging in this scenario.

Surface Crack Detection with Low-cost Photoacoustic Imaging System

International Journal of Technology, 2018
Photoacoustic measurement in an imaging system is a unique method as it uses optical disturbance but observes its effect acoustically. Acoustical observation increases the quality of a measurement by reducing the scattering effect that often occurs in ...

Thermal Resistance of 1D Micron‐Wide Interface Under External Force Modulation

Advanced Materials Interfaces, EarlyView.
A novel TET‐based technique is developed to characterize the interfacial thermal resistance at the microscale. The interfacial thermal resistance is measured at ≈1200–1400 mK/W for natural contact. Externally applied force reduces the thermal resistance dramatically down to ≈125 mK/W.

Effects of Extreme Mirror Downscaling on Open Micro‐Fabry–Perot Spectral Responses and Resonant Mode Profiles

Advanced Photonics Research, EarlyView.
Extreme miniaturization of Fabry–Perot cavities has severe impacts on their spectral response and spatial distribution of the resonant modes. A fully analytical methodology is proposed accounting for the finite borders of the micromirrors to predict this behavior. Model validation relies on comparing with measurements obtained on silicon micro‐cavities
