Abstract :
The spatial mode patterns in an optical microcavity reveal many interesting feature. However, it is not possible to measure these mode patterns directly in most cases. To supplement this limitation, we employ acoustic cavities equivalent to the optical cavities of interest. The pressure field distribution there can be measured using the Schlieren method. We observed chaotic and scar modes in a center-displaced annular cavity.
