Fiber-Optic Bragg Grating Sensor for Photothermally Examinating Moisture of Meat

Photonic Sensors
The illegal water injection into meat not only breaks the market equity, but also deteriorates the meat quality and produces harmful substances. In this work, we proposed a fiber Bragg grating (FBG) sensor that enabled fast, quantitative, and in-situ ...
