This invention introduces a system that combines a diaphragm assembly with an optical coherence tomography (OCT) interferometry-based imaging device to simultaneously measure the vibrations of a structure and the pressure of a fluid in its vicinity. The diaphragm assembly, consisting of a flexible diaphragm within a sealed chamber, is placed near the vibrating structure. The OCT interferometry technique used by the imaging device allows precise measurement of both the diaphragm and the vibrating structure's vibrations by analyzing the phase differences in reflected light beams. This integrated approach reduces the need for multiple sensors and minimizes measurement inaccuracies.
