Abstract: A method for calibrating a velocimetry system, the velocimetry system including at least one camera for imaging an illuminated volume comprising moving particles according to at least two different fields of view, comprising: receiving preliminary imaging equations; simultaneously acquiring sets of images of the illuminated volume from the fields of view; voxelizing the illuminated volume; dividing each voxelized volume into interrogation volumes and generating templates images of each interrogation volume for each field of view using the preliminary imaging equations, identifying a match between given clusters of particles in the corresponding template image and corresponding clusters of particles in the corresponding set of images; determining position disparities between the given clusters of particles within the template image and the corresponding clusters of particles within the set of images; and for each field of view, modifying the corresponding preliminary imaging equations based on the determined d

Abstract: A velocimetry system for measuring the velocity of a moving body propagating through a measurement volume includes a light source for emitting a light beam, a controller for generating a modulation pattern corresponding to a desired set of fringes to be generated in the measurement volume, and a spatial light modulator operatively connected to the controller to receive therefrom the modulation pattern. The spatial light modulator is configured to spatially modulate the light beam according to the modulation pattern in order to generate the desired set of fringes in the measurement volume. Also provided are a light detector for measuring the energy of the light scattered by the moving body as it intersects the fringes, and a data analysis unit operatively connected to the light detector and adapted to determine the velocity of the moving body from at least one fringe characteristic and the energy of the scattered light measured.
