Application of dispersed microresonator based sensor for aerospace-related tasks

A possible application of the dispersed optical microresonator based sensor in aerospace-related tasks is discussed. Configuration of the proposed sensor as a set of spherical glass microparticles together with its working principle is discussed. Sensing capabilities have been verified on examples of detection of temperature variations together with monitoring of the small microparticles adsorption. Thermal sensitivity is determined on the level of 8.6 pm/°C. The possibility for detection of the adsorption of polesterene microparticles (0.9 and 3.27 μ m size) in frequency sweeping and spectrally unresolved illumination schemes have been shown.
