Digital holographic interferometry with CO2 lasers and diffuse illumination applied to large space reflectors metrology

We have addressed this problem by performing phase equilibrium experiments on representative rock types from two key localities: one in Kenya, the Olkaria volcanic field near

Electronic Speckle Pattern Interferometry, Speckle Interferometry et TV Holography: Interférométrie speckle ou en lumière diffuse; Digital Holographic Interferometry:

This paper introduce a new kind of hard samples called corner cases where the entire data is generated (not just a perturbation).. This allows to constraint more easily those data to

So as to compare both methods, the digital hologram is reconstructed using the discrete Fresnel transform with (K,L)0(2048,2048) and with the convolution method so that (K,L)

Compared to digital Fresnel holography, this element is a critical point that influences several aspects of the reconstruction process: filtering/algorithms, aperture,

This paper presents a comparison of image denoising al- gorithms applied to the processing of phase data images degraded with speckle noise in the context of digital holog-

The reflectivity of a diffuse, finite layer of adsorbed polymer is examined, If the bulk solution is semi-dilute, the screening structure generates oscillations in the

intensity of the reference beam was 29.5 mW cm~~, while the average intensity of the object beam in the hologram plane was 5.0 mW cm~~- Two reconstructed images of the test chart.
