Particles About to Alight on a Whispering-Gallery Resonator

Caption

Particles that alight on the resonator disturb a light wave circulating in the torus (whose nodes and anti-nodes are visible on the torus's base) and these disturbances provide information about the particle's size. The pink line receding into the distance is an optical fiber through which light is coupled into and out of the torus.
