Abstract: Drift is a significant issue that undermines the reliability of gas sensors. This paper introduces a probabilistic model to distinguish between environmental variation and instrumental drift ...

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 ...

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 ...
