“…The first one, the laser wavelength sweeping technique, delivers a set of the spectral maps together with the corresponding time points. This data is processed by the sequential analysis of each resonator's spectrum and the respective spectral changes are characterized as described in detail in [21]. Initially, each WGM spectrum associated with an individual resonator is denoised by the stationary wavelet transform.…”

Applicability of the whispering gallery mode sensor in the form of the multiresonator imaging device for the atmosphericrelevant parameters monitoring has been demonstrated. The sensor design and the appropriate techniques for sensing data collection have been discussed. The sensor performance has been numerically and experimentally studied on examples of the temperature variation detection and the monitoring of small spherical microparticles (< 3 µm) that have been used to mimic the particulate contamination of the environment. The thermal sensitivity of the sensor on the level of 8.6 pm/ • C has been experimentally demonstrated. The experimental results on the distinguishing of the microparticle concentrations (0.5% and 1%) via the wavelength sweeping technique and the results on the single particle detection under illumination at the fixed wavelength have been shown.
