Optical Sensing refers to the use of optical principles and technologies to capture, measure, and analyze physical or chemical properties of the surrounding environment. Optical sensing systems leverage the interaction of light with materials to obtain information about the characteristics of objects, substances, or phenomena. Optical sensing technologies continue to advance, leading to innovations in diverse fields and contributing to the development of more efficient, accurate, and versatile sensing systems.


Wavelength Modulation Spectroscopy Enhanced by Machine Learning for Early Fire Detection

We proposed and demonstrated a new machine learning algorithm for wavelength modulation spectroscopy to enhance the accuracy of fire detection. The result shows more than 8% of accuracy improvement by analyzing CO/CO 2 2f signals.
