摘要：

We report on the progress of an optical tag designed to indicate the presence of HF. The approach we followed uses a high spatial frequency grating consisting of lines of conductive polymer. The conductive polymer has been designed to be sensitive to HF; changing its conductivity upon exposure. This material change results in a change in the polarization response of the grating which can be read out remotely using optical techniques. The use of a polarization response makes the signal more robust to intensity fluctuations in the background or interrogation system. Additionally, the use of optical interrogation allows for standoff detection in instances where hazardous conditions may be present. A review of the material development work will be presented as well as the device fabrication efforts. Examples of material and device responses will be shown and directions for further investigation discussed.
