This thesis introduces the research history of sonoluminescence, the properties and equipments of single-bubble sonoluminescence and the factors affecting the amount of light emission. Based on the experimental realization of SBSL, the experiment in this thesis is to confirm the coherence between the emitting frequency and the driving cycle of SL. Under this feature ,we established the programme of the experiment that measure the angular correlations in SBSL , built the experimental devices and conducted initial measurements .Then we got the conclusion that there is a presence of non-spherical symmetry in the process of SBSL .
