This paper presents a measurement of three-dimensional particle distribution by tomographic digital holography. Holographic patterns of particles (particle Reynolds number Rep=0.79, average diameter dp=73.5 μm) settling in a static flow were recorded by two high speed cameras orthogonal to each other. Cameras were calibrated by a proposed method using a calibration device and a pattern matching. The calibration accuracy of the method is within 0.34 times of particle diameter.
