1. A system for measuring acoustic wave vectors in a fluid, the system comprising:
a first camera and a second camera, each configured to be placed in the fluid to record any movement of at least one particle suspended in the fluid in response to any disturbance of the fluid by an acoustic wave;
a light source configured to be placed in the fluid; and
a controller configured to:
control the first camera;
control the second camera;
control the light source;
process images provided by the first camera and second camera to determine an acoustic wave vector of the acoustic wave based on the measurement movement of the at least one particle.
