Dual-wavelength digital holography for 3D particle image velocimetry: experimental validation

摘要

A multi-exposure digital in-line hologram of a particle field is recorded by two successive pulses of different wavelengths. During the reconstruction step, each recording can be independently analyzed by selecting a given wavelength. This procedure enables avoiding the superimposition of particle images that may be close to each other. (C) 2015 Optical Society of America
