Analyzing two hetero-core spliced low-cost set-up in assessing temperature

Abstract

Accurate measurement of temperature is very essential in laboratory scale to industrial sector. Extensive research is under way in achieving higher accuracy. In this direction, we present a comprehensive and procedural performance analysis of two hetero-core spliced system in measurement of temperature in identical domain. Employing a single mode-multimode-single mode (SMS) and its’ reverse arrangement multimode-single mode-multimode (MSM), we measure temperature in the range of 30°–80 °C. Through a facile intensity interrogation mechanism, the two arrangements are compared in terms of their sensing characteristics. It is found that the latter outperforms the former in terms of linearity. Apart from this, the resolution is also higher in case of the latter. All these findings are procedurally investigated and interpreted.
