  1. 25. Cancer Holography for Personalized Medicine

    Holography, optical processing and imaging
    Regular Talk

    This paper reviews the uses of optical holography in cancer biology and personalized medicine. Holography of living tissue occurs in two stages: a coherence-domain stage with depth-selection through holographic interferometry (hologram writing), followed by a reconstruction stage (hologram readout). With its beginnings in photorefractive holography, the writing and the readout of cancer...

    A transient detection imaging system (TDI), also known as optical novelty filter, is an adaptive interferometric device that detects temporal changes in a scene while suppressing its static parts. Removal of background improves contrast and helps visualizing and measuring intensity and phase. Most TDI systems are based on photorefractive two-wave mixing. Previous works rely on conventional...

    The use of composite materials for structural elements in high value structures and components (e.g. wind turbines blades, composite parts in aircrafts …) requires fast and reliable tools for assessing their structural integrity.
    The inspection method proposed in this work is based on the detection of defect-induced elastic cross-modulation phenomena using a vibrometric scheme that makes use...

    Coherent detection in optical beams requires measuring the optical phase with an interferometric setup, which implies superposing the optical wavefronts of the signal and reference beams. Because of its intrinsic nature, optical phase detection rapidly undergoes degradation if the interfering beams are not spatially uniform, as when propagating through scattering media. In this case a...

  5. 8. Photorefractive holography for optical reconstruction of structured light
    Dr Marcos Gesualdi (Universidade Federal do ABC (UFABC))
    Holography, optical processing and imaging
    Regular Talk

    This work presents the photorefractive holography possibilities of the optical reconstruction of structures light. In PRH, the hologram of a non-diffracting beam is optically constructed ('recording') and reconstructed ('reading') in a nonlinear photorefractive medium. The experimental realizations of many types of the structured light, for instance: non-diffracting beams, vortex beams and...
