“…Noise can be added as well. As in [20], we assume that multiple scattering can be neglected (i.e., the part of the light diffracted by the first object and then by the second object). The incident beam is a Gaussian beam.…”

“…Research activities in this field have many orientations: some articles treat the elaboration of models to compute and predict holograms. Others emphasize on the development of new image processing techniques for object reconstruction, estimation of ultimate sensitivity of the set-up, or design of specific configurations for in situ applications [15][16][17][18][19][20]. In digital holography, the in-line configuration allows the design of a simple set-up with a relatively low number of optical elements.…”

We present the development of a numerical simulator for digital in-line holography applications. In-line holograms of arbitrarily shaped and arbitrarily located objects are calculated using generalized Huygens-Fresnel integrals. The objects are 2D opaque or phase objects. The optical set-up is described by its optical transfer matrix. A wide variety of optical systems, involving windows, spherical or cylindrical lenses, can thus be taken into account. It makes the simulator applicable for design and description of in situ experiments. We discuss future applications of this simulator for detection of nanoparticles in droplets, or calibration of airborne instruments that detect and measure ice crystals in the atmosphere.

In this publication, the modelisation of an air bubble as inclusion in a droplet is treated from scalar theory point of view (Fresnel's theory). The elaborated model is compared with Lorenz-Mie scattering theory and with an experimental results. Circle polynomials and scaled pupil function are the background of this work to take into account the critical angle effect that arises at a transition from a higher index to a lower index medium.

“…Since its discovery, digital holography has been applied to the experimental study of fluid flow, to measure the size, the particles coordinate's and their speeds [7,8]. Indeed interferogram analysis can be used in a great deal of cases, to deduce the properties of the studied fluid, in particular the space positions (x, y, z) and sizes of the moving liquid drops [9,10]. These parameters, known over time, allow the deduction of the flow velocity and the viscosity parameters.…”

“…The sliding window was optimized in order to be independent of the recording distance. In order to validate the proposed method, we used it to analyze simulated and measured holograms made by other authors [9,14] and compared their results with ours. Theory AR method for interferometric signal analysis AR models are known to perform well in the extraction of frequencies from short data records.…”

We propose in this paper a digital hologram analysis based on a parametric method with the purpose of determining the distance between a small spherical particle and the sensor. The in-line Fraunhofer hologram of the particle is considered. The parametric method is implemented with a sliding window to extract the frequency of the chirped signal. A good agreement between simulations and results obtained by other authors is observed.
