This paper combines the internal refractive index characteristics of the optical fiber Fabry-Perot (F-P) cavity and the response mechanism of polyaniline (PANI) and reactively deposits PANI
Brief theory of sensing principle, fabrication method, applications, advantages and disadvantages of the different fiber‐optic sensors, are addressed.
This review categorizes optical fiber pH sensors into six primary types—fluorescence-based, absorbance-based, Surface Plasmon Resonance
The pH meter consist of a LED and photodiode which excites the compounds in the pH sensor and detects its luminescence emission. The excitation and emission light is transmitted via an optical
A fiber optic pH sensor based on single fiber phase fluorescence lifetime measurements of commercially available fluorescence indicators is described. The apparatus is a straightforward modification of an

This review categorizes optical fiber pH sensors into six primary types—fluorescence-based, absorbance-based, Surface Plasmon Resonance (SPR), Fiber Bragg Grating (FBG),
Here, we present the development of compact pH fiber probes by integrating silica optical fiber with a colorimetric pH indicator. Our approach involves cross-linking the pH indicator with a
Optical pH sensors are devices that use light to measure the acidity or alkalinity of a solution. These sensors work based on the principle of optical sensing, which involves the interaction
An early book on fiber optic chemical sensors and biosensors, published in 1991, contains a section on pH sensors that also includes the fundamentals of indicator-based pH sensors.
