Abstract: An optical sensor that can measure multiple parameters is a promising area of research. This can also be attributed to the fact that monitoring two or more measurands at the same time is ...
Abstract: Long-period gratings (LPGs) are promising photonic chemical sensors since they can excite cladding modes that interact with the surrounding medium. Small-period long-period gratings (SP-LPGs ...
The Brix scale, derived from the refractive index of a solution at 20 degrees Celsius (68 Fahrenheit), is widely known. Originally, it was established by determining the weight percentage of sucrose ...
