“…Deyhaa A. Resen et al [ 159 ] proposed and demonstrated a heterodyne method for humidity measurement, using an FBG to filter and shift the center wavelength of one path of light relative to the other. A sensitivity of 0.142 GHz/%RH between 23.8%RH and 83.4%RH was reported, with a dynamic range of 23.8%RH–83.4%RH.…”

Optical humidity sensors have evolved through decades of research and development, constantly adapting to new demands and challenges. The continuous growth is supported by the emergence of a variety of optical fibers and functional materials, in addition to the adaptation of different sensing mechanisms and optical techniques. This review attempts to cover the majority of optical humidity sensors reported to date, highlight trends in design and performance, and discuss the challenges of different applications.
