The present invention relates to an improved system for probing bubble dynamics in a mixing vessel made of a transparent material. The system preferably comprises an optical recording means fixed by a bracket in the mixing vessel at a region at a depth substantially above an impeller of the mixing vessel configured for recording a still image and a video of subject bubbles therein; and a strobe light source having an adjustable flashing frequency remotely positioned outside of the mixing vessel relative to the optical recording means configured for emitting a flash light of a predefined flashing frequency towards the region in the mixing vessel through a light converging medium.
