1. Recent Progresses in Digital Holographic Microscopy with Spatial Partial Coherent Light and Applications

Author

Ahmed El Mallahi, Frank Dubois, Christophe Minetti, and Catherine Yourassowsky

Subjects
Microscope, Materials science, Optics, law, business.industry, Holography, Digital holographic microscopy, business, Laser beams, Partial coherence, law.invention
Abstract

We investigate the use of partially coherent source for digital holographic microscopes (DHM). Recent progresses and applications will be presented as the automated 3D detection and classification of particles or the analysis of vesicle suspension.

Subjects
Optics, Computer holography, Materials science, business.industry, Vesicle, Microscopy, Biophysics, Digital holographic microscopy, Shear flow, Suspension (vehicle), business, Laser beams, Digital holography
Abstract

Vesicles are simplified models of living cells such as red blood cells. Hydrodynamical effects lead to a specific structure of the suspension that is analyzed by digital holographic microscopy on earth and in microgravity conditions.

Abstract

We investigate the use of partially spatial coherent illuminations for digital holographic microscopes (DHM) working in transmission. The major advantage is reduction of the speckle noise making it possible high image quality for biomedical applications.
