Abstract

A digital micromirrors device is used to reproduce the speckle-like interferometric images that would produce rough particles. Time-dependent index inhomogeneities induced by a flame are added between the particle and the imaging system. The size measurements deduced from 2D-Fourier analysis of the interferometric patterns show a less than 10% error when the programmed object is fixed, and a less than 20% error when a scintillation of the object is programmed.

NameDescription
Visualization 1       In-focus images of a cross (programmed on the DMD), recorded on the CCD sensor when index inhomogeneities are present between the DMD and the lens.
Visualization 2       Left part : Interferometric out-of-focus images of the cross (programmed on a DMD), recorded on the CCD sensor when index inhomogeneities are present between the particle and the sensor. Right part : corresponding 2D-Fourier transform of the interferometric pattern.
Visualization 3       In-focus images of the cross (programmed with a scintillation effect), recorded on the CCD sensor when index inhomogeneities are present between the DMD and the lens.
Visualization 4       Left part : Interferometric out-of-focus images of the cross recorded on the CCD sensor with « scintillation effect and when index inhomogeneities are present between the particle and the sensor. Right part : corresponding 2D-Fourier transform of the interferometric pattern.
Visualization 5       In-focus images of a pair of stick-shaped particles (programmed on the DMD) recorded on the CCD sensor in presence of index inhomogeneities between the DMD and the lens.
Visualization 6       Left part : Cropped interferometric out-of-focus images of the pair of stick-shaped particles (programmed on the DMD) recorded on the CCD sensor in presence of index inhomogeneities between the DMD and the lens. Right part : corresponding 2D-Fourier transform of the interferometric pattern.
