Abstract

In order to achieve online non-destructive testing of mold growth and detection on wooden cultural relics, this paper proposes a reflective fiber optic sensor composed of one transmitting fiber and six inclined receiving fibers. The sensor is used to conduct experimental research on the growth of Trichoderma longibrachiatum and Cladosporium cultivated on wooden samples, and the relationship between the spectral information, absorbance, and growth height of the two molds is obtained. The experimental results indicate that the sensor can identify and accurately measure mold on the surface of wooden cultural relics, and the proposed sensor has good application prospects in the field of cultural relic detection.
