Article
This article presents analysis of using fiber Bragg gratings for deflection distance measurement of a material subjected to bending force. The measurement method used in presented research is based on the phenomenon of the back reflection of Bragg wavelength, which enables a point reading of strain and temperature. The article presents the effect o...
Article
This paper reports on examination of the latest generation of telecom optical fibers for the Brillouin backscattering strain sensor application. Over 30 fibers from 5 different manufactures have been tested in terms of their ability to create a stable and accurate strain sensor. It has been proved that fibers that belong to the same standard, accor...

In this paper, the fabrication and characterization of a temperature sensor based on periodically tapered optical fibers (PTOF) are presented. The relation between the geometry of the sensors and sensing ability was investigated in order to find the relatively simple structure of a sensor. Four types of PTOF structures with two, four, six and eight...

This paper examined the impact of optical fiber sensor design, and its integration to PVC (polyvinyl chloride) sheet piles, on deflection and strain monitoring. Optical fiber sensors based on Brillouin light backscattering (BLS) were prepared, as they can provide accurate strain and deflection measurement results. However, depending on the applicat...
Article
In this paper the detailed description of tapered optical fiber (TOF) fabrication process with the use of fusion splicer is given. Developed method allows TOF fabrication of a given waist region length l up to 4 mm with a micrometers resolution, while their diameters were 41 μm ± 5 μm. The TOF mean symmetry coefficient was scoef = 1.05. The Inserti...
Article
Monitoring and controlling the position of fibre optics connectors is a very important issue. Both autonomy and remote control of such a system are very desired and therefore energy independence must be provided. In this paper the design of an optical power supply system is given. A new idea of using the WDM technique in a power supply block is inv...
Article
Fiber optic sensors are very promising because of their inherent advantages such as very small size, hard environment tolerance and impact of electromagnetic fields. In this paper three different types of Intensity Fiber Optic Displacement Sensors (I-FODS) are presented. Three configurations of I-FODS were realized in two varieties. In the first on...

An overview of the achieved Inverse Spin Hall Effect voltage (VISHE) is presented to find upper limit of this ISHE voltage. Comprehensive review confirms that the most significant spin systems are based on YIG substrate. The Pt ISHE interfaces are the most popular, however, the best result was reported for the Ir20Mn80 ISHE interface. Moreover, in...
Article
RFID identification of fiber optic connectors system is developed. This system should be autonomous and it must allow to be implemented in distribution part of passive optical networks (PON). The conventional power source should not be considered, due to the lack of electricity in PON. Therefore the alternative power source is proposed to power thi...
Article
Purpose The purpose of this paper is to develop identification system for fiber optic connectors in passive distribution cabinets. The system should have alternative power supply and wireless communication unlike the identification systems commercially available, which will make the system fully autonomous. Design/methodology/approach Detailed p...

In almost all of non-invasive techniques, fiber optic sensors may be the most promising ones because of their inherent advantages such as very small size and hard environment tolerance. Proximity sensors based on optical fiber are highly required especially in the impact area of electromagnetic fields. In this paper three different types of fiber...

Fiber Distribution Cabinets (FDC) monitoring systems are increasingly popular. However it is difficult to realize such system in passive FDC, due to lack of source of power supply. In this paper investigation of four different DC power supplies with optoelectronic transducers is described. Two converters: photovoltaic power converter and PIN photod...

In this paper, proximity sensors based on ball-lensed single-mode fibers (SMF) are described. Two types of sensors are presented: (1) Type A with one transmitting and four receiving optical fibers and (2) Type B with one transmitting and eight receiving optical fibers. In both types ball-lensed optical fibers are used as a receiving line. Sensitivi...

In this paper the process of modeling and implementation of ball-lensed single mode fibers (SMF) is discussed. Four types of microlenses were made in Optical Fiber Technologies Laboratory (OFTL) at Lodz Technical University of Lodz (TUL). Focal lengths of lenses determined in simulations were compared with the focal determined during measurement. P...

Reflective sensors involving optical fibers are very popular due to low cost and EMI insensitive. In this paper, a new concept is described regarding proximity sensors based on ball-lensed optical fibers (PSBBOF). Two types of sensors are presented: (1) Type A with one transmitting and four receiving optical fibers and (2) Type B with one transmitt...
