This study proposes a three-dimensional (3D) visualization method that is combined with the hydrogen bubble method (HBM) and digital in-line holography using two-wavelength reconstruction. In this method, the 3D distribution of hydrogen bubbles generated by HBM is measured by digital holography. Vortex shedding from a circular cylinder is observed in an open channel. 3D flow structures of the cylinder wake are successfully visualized.
