Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of ...

Biosensors are helping people with chronic conditions worldwide live better lives. However, their measurement accuracy has often been relatively low, limiting the range of possible applications.

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Abstract: Arc faults are a major cause of electrical fires. Due to the diversity of load types, existing arc fault detection (AFD) methods struggle to cover all load types, making the development of a ...

Abstract: Aiming at the demand of oxygen partial pressure measurement in aerospace and aviation, a tunable diode laser absorption spectroscopy (TDLAS) technique is proposed to realize the oxygen ...
