Deconvolution for digital in-line holographic microscopy
aot, 2013 Abstract To improve the resolution in point source digital in-line holography, we present two deconvolutions, one for the illumination system (coherent or partially coherent light source such as a laser or diode and pinhole) and one for the finite numerical aperture of the hologram.

Separation of overlapped particles in digital holographic microscopy
Optics Express, 2013 In this paper, we present a procedure to separate aggregates of overlapped particles in digital holograms, based on a focus plane analysis applied to each particle. The method can be applied either on phase or on amplitude objects, according that each object has a border in one focus plane. Numerical simulations are performed to quantify the robustness

Micro‐size aperture surface acoustic wave generator for cell lysis
Droplet, Volume 4, Issue 3, July 2025.Micro‐size aperture interdigitated transducer for cell lysis of cell inside droplets. Abstract The breakage of the cellular membrane for releasing intracellular material is the starting point for several diagnostics or treatment processes. Surface acoustic waves can provide a novel and chemical‐free approach by inducing acoustic streaming generating ...
