The combined use of digital holographic microscopy and computer tomography, here named digital holographic micro-tomography, is used to examine the interior of transparent channels. The proposed method is used to identify ...

Weakly-scattering objects, such as small colloidal particles and most biological cells, are frequently encountered in microscopy. Indeed, a range of techniques have been developed to better visualize these phase objects; ...

Due to the sequential-readout nature of most CMOS sensors, each row of the sensor array is exposed at a different time, resulting in the so-called rolling shutter effect that induces geometric distortion to the image if ...

The relative amount of biomass in a body of water is one of the various indicators widely used in water quality evaluation. This implies complex tasks such as identification and characterization of microorganisms and ...

In this paper, processing methods of Fourier optics implemented in a digital holographic microscopy system are presented. The proposed methodology is based on the possibility of the digital holography in carrying out the ...

The use of multiple wavelength illumination in digital in-line holographic microscopy is presented. A biological sample is illuminated sequentially with three different optical sources and the separate holograms reconstructed ...

(Eng) The principles and some applications of the digital lensless holographic microscopy (DLHM) to study the microworld are shown in this paper. The recording and reconstruction processes of the DLHM are analyzed to study ...
