Abstract:
A brief review of the principles of constructing optical gas-analyzing sensors is presented. It is noted that the influence of humidity of the surrounding gas environment during gas analytical procedures using solid-state gas analytical sensors is a serious technological problem. It is shown that sensors of particular interest are functioning on the principle of absorption of the primary light flux because of their reduced sensitivity to fluctuations in the humidity of the carrier gas. The design and the gas analytical properties of an optical chemical sensor are described. Ammonia was used as

Abstract:
The main features of the construction of gas analytical leak detection systems are noted, from the point of view of the sensitive element and the test substance (gas) used in the leak tightness control. It is shown that when checking the tightness of functioning systems, the standard leak detection equipment is of little use because it is impossible, in most cases, to use the specific test gases necessary for its operation. The use of solid-state gas analytical sensors for the construction of leak detection systems for operating process equipment is proposed. It is shown that one of the most s

Abstract:
Molecularly imprinted polymers (MIPs) can be combined with optical fibers (OFs) to create various sensor configurations, yielding low-cost and highly sensitive extrinsic and intrinsic sensors. In this work, an MIP-based extrinsic optical fiber sensor is obtained by two silica OFs connected via an optical waveguide using an MIP as a core of micrometer size (micro OF-MIP-OF sensor). The proposed sensing approach can be used only with MIP receptors and implements an intensity-based sensor configuration. MIPs present several advantages over bio-receptors and can be exploited to realize novel sensi

Strains induced upon exposure to hydrogen with varied concentrations can be monitored by IFPI sensors. The fiber sensor shows a repetitive and reversible response when exposed to a low level (1–6%) of hydrogen gas.

Abstract:
Optical chemical sensors are widely applied in many fields of modern analytical practice, due to their simplicity in preparation and signal acquisition, low costs, and fast response time. Moreover, the construction of most modern optical sensors requires neither wire connections with the detector nor sophisticated and energy-consuming hardware, enabling wireless sensor development for a fast, in-field and online analysis. In this review, the last five years of progress (from 2017 to 2021) in the field of optical chemical sensors development for persistent organic pollutants (POPs) is provided.

A novel method for modification of the polymer cladding of an optical fiber has been developed for use in distributed chemical sensing. The usefulness of the new technique is illustrated by means of a distributed sensor for ammonium ions based on a 9 m long plastic-clad silica fiber modified with phenol red. The stability of the immobilized indicator made it possible, for the first time, to use a chemically modified fiber for the reversible detection of ammonium ions in highly alkaline solution (pH 11–14).

This thesis describes the development, characterisation and application of large diameter multimode plastic optical fibre (POF) sensors using evanescent field modulation. The exposed polymethylmethacrylate (PMMA) core of the POF fibre forms the sensor interface that detects refractive index changes of a measurand acting as the cladding. When a liquid measurand is used, the sensor can detect changes in refractive index, absorption and suspended particulates. It is this simple mechanism by which the evanescent field POF sensor operates. The evanescent field POF sensor has been characterised for

Surface plasmon resonance (SPR) sensors using multiwavelength light coupling are investigated to probe changes in refractive index that occur as a result of chemical or biochemical processes. Traditional SPR sensors have used angle modulation to facilitate detection at the sensor surface; however, the multiwavelength approach is novel and brings new functionality to SPR sensors. The multiwavelength sensors are constructed on both fiber optic and bulk waveguides such as prisms. A thin metal film is deposited on the waveguide surface to support the surface plasmon (SP) mode.

A sensor is described which utilizes the phenomenon of surface plasmon resonance to detect changes in refractive index of chemical or biochemical samples applied to a surface modified optical fiber. The sensor is constructed by polishing a short section of the lateral surface of an optical fiber to its evanescent field surrounding the fiber core. One or more thin films are applied to the polished section of the fiber to produce the sensing element. One of the films is the metal silver, which acts as the support for the surface plasmon.
