Acousto-holographic optical tweezers 

    Bola Sampol, Raúl; Treptow, Dorian; Marzoa Domínguez, Antonio; Montes Usategui, Mario; Martín Badosa, Estela (2024-01-30)

    Acousto-optic deflectors (AODs) allow the creation of multiple optical traps by time-sharing, that is, by rapidly cycling the laser focus between designated spatial locations. The traps thus formed are not permanent. In ...

    Artifact-free holographic light shaping through moving acousto-optic holograms 

    Treptow, Dorian; Bola Sampol, Raúl; Martín Badosa, Estela; Montes Usategui, Mario (2022-02-21)

    Holographic light modulation is the most efcient method to shape laser light into well-defned patterns and is therefore the means of choice for many intensity demanding applications. During the last two decades, spatial ...

    Rapid quantification of 3D ultrasound fields with wavefront sensing and Schlieren tomography 

    Colom, Mateu; Ricci, Pietro; Duocastella, Martí (2024-09-25)

    The rapid and precise characterization of three-dimensional (3D) pressure fields inside water is paramount for ultrasound (US) applications in fields as relevant as biomedicine and acoustic trapping. The most conventional ...

    Video-rate quantitative phase imaging with dynamic acousto-optic defocusing 

    Alexandropoulos, Christos; Duocastella, Martí (2023-09-08)

    Various quantitative phase imaging techniques exist capable of characterizing transparent and low-contrast samples without the addition of dyes or fluorescent probes. Among them, the transport of intensity equation (TIE) ...
