A holographic particle-image velocimeter is proposed for 3-D fluids velocity fields study. A low-f-number optical arrangement is used that records two views of flow volume at two times on a single holographic plate, and one at a time reconstructs those views using phase-conjugate multiplexed image reconstruction. Improvements in depth of focus, signal-to-noise ratio, and image resolution are reported.
