Abstract In the experiment of measuring air-borne sound pressure by photon correlation spectroscopy in free field, the accurate measurement of the angle between two beams has a great influence on the result of sound pressure measurement. By using the magnified imaging of the microscopic objective, the fringe spacing in the interference area is measured and the angle between the two beams is calculated with high accuracy. Firstly, the influence of the interference spot shape and the uniformity of the fringe spacing on the sound pressure measurement is studied to optimize the optical configuration. Then, the USAF test target is employed as the sample to calibrate the amplification factor of the system. Finally, the air-borne sound pressure in free field is measured by the photon correlation technology. The experimental results showed that, compared with the angle obtained by traditional tri-angle method by measuring the spatial propagation distance of light, the angle obtained by this method improved the accuracy of air acoustic pressure measurement.
