Abstract

The effect of signal amplitude modulation in single bubble sonoluminescnece was studied. Sonoluminescence is the phenomena of emitting light when bubbles in a fluid are exposed to high frequency sound pressure. A bubble was introduced into a dynamic environment and the effects of amplitude modulation on the properties of the emitted light were observed. A photomultiplier was used to collect the emitted light. The measured SBSL signal appeared as a train of flashes for modulation frequencies below 250 Hz, as a continuous modulated signal for higher frequencies.
