An Investigation on Optical Measuring Systems using Different Types of Optical Fibre Links and Performance of Optical Sensors

Mothana A. Hassan [2]

Abstract: One of the most notable characteristics of free-space optical measurement systems is their capability for directly affecting those assessment systems which operate within the context of propagation paths. As the literature attests to, light is dispersed or interfered with as it propagates through an optical fibre, the consequence of which is that the signal at the output end experiences a level of loss. However, the degree to which loss occurs as part of this process can be detected with appropriate technologies, and each error can they be afforded with an uncertainty outcome. Optical measurement systems that operate on this principle of light transmission through fibre optic links prove significant in extracting data that will be pertinent for the mainframe analysis. In view of these considerations, the purpose of the present paper is to investigate and provide an account of the immediate determinations associated with the use of single-multi-mode optical fibres, along with their impacts on the collection of information from high-speed optical measurement instrument links. In addition, the paper gives an overview of several design facets of the design methodology, along with the experimental measurement results of a fibre-optic-based surface topography measurement sensor (with the capability of measuring surface roughness). At the end of the paper, it will be stressed that further research is required to determine whether single- or multi-mode optical fibre sensors are more appropriate with respect to certain categories of instrument, in particular those which are now being utilised heavily in the context of embedded metrology applications.
