| description | Proposed is a gas concentration monitoring method that is based on the dispersion of Bloch surface wave. Different from the conventional sensing method using a single parameter such as wavelength or angle, all measured data was fully analyzed from a two-dimensional reflection intensity curve of a Bloch surface wave by mutual reflection intensity, which can reflect changes in either the refractive index or the airflow motion. This method does not require recording specific wavelength or incidence angles and measurement of small wavelengths or angle deviations. Our airflow monitoring device has a detection limit of 1.14 × 10−4RIU and good linearity in an open environment with high noise levels. However, in a closed environment, we achieved stable monitoring of the dry ice sublimation process and prediction. |
