“…Coherent Rayleigh DFS gains more attention for this application because it is three orders of magnitude more sensitive to strain than Brillouin DFS [75]. Coherent OTDR and coherent OFDR techniques were used to demonstrate fully distributed humidity and hydrogen sensing [76,77,78]. The strain change of a polyimide-coated fibre was measured using a commercially available OFDR system, exhibiting a near-linear response to relative humidity range from 15 to 92% [78].…”

Chemical sensing is of great importance in many application fields, such as medicine, environmental monitoring, and industrial process control. Distributed fibre-optic sensing received significant attention because of its unique feature to make spatially resolved measurements along the entire fibre. Distributed chemical sensing (DCS) is the combination of these two techniques and offers potential solutions to real-world applications that require spatially dense chemical measurements covering large length scales. This paper presents a review of the working principles, current status, and the emerging trends within DCS.
