Abstract

FBG is used to construct pH and strain fiber optic sensors to realize online detection of oxalic acid corrosion process of sandstone artifacts. The pH fiber optic sensor uses a PVA/PAA hydrogel as the sensitive material and the fiber optic is held in a half-open PTFE tube by a UV adhesive. The de-coated FBG is fixed to the surface of the relics with epoxy resin to detect strain in the relics. The research results of this paper will provide an important reference for analyzing the acid dissolution corrosion mechanism of stone cultural relics and preventive protection of cultural relics, and promote the scientific and technological development and engineering application of physicochemical FBG sensors.
