Long exposure time Digital In-line Holography for the trajectography of micronic particles within a suspended millimetric droplet

Digital In-line Holography is used for the three-dimensional tracking of micronic particles in a millimetric droplet. The 3D location of the inclusions is realized through the digital reconstruction of holograms using the 2-Dimensional Fractional Fourier Transform. The trajectory of the particles in...

Description
Summary:Digital In-line Holography is used for the three-dimensional tracking of micronic particles in a millimetric droplet. The 3D location of the inclusions is realized through the digital reconstruction of holograms using the 2-Dimensional Fractional Fourier Transform. The trajectory of the particles inside the droplet is obtained using a long exposure scheme.
