The article discusses the research and development of a low-cost, high-precision polarization interferometric fiber array temperature sensing technology using polarization-maintaining fibers for small-scale applications like power equipment monitoring.

Summary

This paper researches a low-cost, high-precision fiber optic temperature sensor array for monitoring power equipment using polarization-maintaining fibers and polarization interference. It finds that shorter sensor probes (like 1 cm) have a wider temperature measurement range with good accuracy (around 0.3 ℃ error), making it suitable for small-scale applications.
