Miniaturised Optical Fibre Sensor for Dew Detection Inside Organ Pipes
Figure 3
Response curve of the optical fibre
sensor following a decrease of the temperature of the aluminium block from to and back again to . The graph shows also the tracings of both
the temperature and the relative humidity of the aluminium block (named
internal RH and internal T, resp.) and of the external environment (named
external RH and external T, resp.). The left y-axis is related to the optical
signal, whereas the y-axis on the right is for the temperature and the related
humidity.
