Abstract

An innovative multibeam holographic particle velocimetry technique is described for three-dimensional flow-velocity measurement. Characterized by suppressed speckle noise, decreased image depth of field, and efficient use of laser energy, the multibeam holographic particle velocimeter overcomes drawbacks of techniques that are based on conventional in-line and off-axis holography.
