Measurement of full-polarisation parameters using in-line fibre-optic polarimetric device

Jaroszewicz L. R., Marć P.

Opto-Electronics Review

2002

Vol. 10, No. 3

199-207

The in-line fibre-optic polarisation analyser enabling measurement of full polarisation parameters of light propagated in optical fibre is presented in the paper. This device uses a standard single-mode optical fibre in a system of the polarimetric configuration. Introduction of controlled birefringence in such a fibre and application of an appropriate polariser set at the end of the system allow to get full information about polarisation parameters to obtain. Evaluation of any changes of the state as well as the degree of polarisation have been achieved by application of an appropriate detection system and numerical calculation based on the coherence matrix theory. Finally, some experimental results of the system performance and determination of the main errors are presented.

Polarimetric optical fiber sensors for hydrostatic pressure and dynamic strain measurement

Woliński T.R., Konopka W., Domański A.W.

Optica Applicata

2001

Vol. 31, nr 2

385-398

Polarization properties of the highly birefringent fibers and highly birefringent fiber-based polarimetric smart structure are discussed in view of potential applications to polarimetric optical fiber sensors for hydrostatic pressure and dynamic strain measurement.

In-line fibre-optic ellipsometer for sensor application

Kieżun A., Jaroszewicz L. R.

Opto-Electronics Review

2000

Vol. 8, No. 2

175-180

Theoretical and experimental analysis of a new fibre-optic ellipsometer in polarimetric configuration is presented. The main idea of a system operation is based on controlled birefringence introducing on a piece standard single-mode fibre. Estimation of a real-time changes in polarisation state parameter, and the ellipsometer measurement have been done for the known induced birefringence. In the paper, research of the constructed in-line system as a new ellipsometer detection system for the fibre-optic sensor application is also presented.
