摘要
Spherical microresonators are high sensitivity sensors for the measurement of important physical quantities e.g. temperature or pressure. Measuring methods based on single optical resonators need expensive and delicate laser systems or spectral devices. The aim of this paper is to present a novel multi-purpose sensing technology based on whispering gallery modes in spherical microparticle arrays. Examples for different applications are given to prove the flexibility and usability of the method.
