Twin-image noise reduction by phase retrieval in in-line digital holography [PDF]
, 2005 14 pagesInternational audienceIn-line digital holography conciles the applicative interest of a simple optical set-up with the speed, low cost and potential of digital reconstruction. We address the twin-image problem that arises in holography due to the

Multi-Object Deep-Field Digital Holographic Imaging Based on Inverse Cross-Correlation
Applied Sciences, 2023 To address the complexity of small or unique reconstruction distances in digital holography, we propose an inverse cross-correlation-based algorithm for the digital holographic imaging of multiplanar objects with a large depth of field. In this method, a

Imaging velocities of a vibrating object by stroboscopic sideband holography [PDF]
, 2012 We propose here to combine sideband holography with stroboscopic illumination synchronized with the vibration of an object. By sweeping the optical frequency of the reference beam such a way the holographic detection is tuned on the successive sideband ...

Lensfree on-chip microscopy over a wide field-of-view using pixel super-resolution. [PDF]
, 2010 We demonstrate lensfree holographic microscopy on a chip to achieve approximately 0.6 microm spatial resolution corresponding to a numerical aperture of approximately 0.5 over a large field-of-view of approximately 24 mm2.

Feed particle size evaluation: conventional approach versus digital holography based image analysis
Italian Journal of Animal Science, 2010 The aim of this study was to evaluate the application of image analysis approach based on digital holography in defining particle size in comparison with the sieve shaker method (sieving method) as reference method.

Shot Noise in Digital Holography [PDF]
, 2010 We discuss on noise in heterodyne holography in an off-axis configuration. We show that, for a weak signal, the noise is dominated by the shot noise on the reference beam.
