Focusing through scattering media with rapid characterization Engineering essay
We introduce a phase control holographic technique to characterize scattering media with the aim of focusing light through them. The system generates computer-generated holograms implemented through a deformable mirror device DMD based on microelectromechanical technology. The DMD can be updated at high data rates. Here we present a full-phase digital optical phase conjugation method based on off-axis holography for single-shot optical focusing through scattering media. By using off-axis holography in combination with graphics processing unit-based processing, we take advantage of the single-shot full-phase measurement while using parallel, electrical engineering and systems science image and video processing. arXiv 2111.14916 eess, submitted, title: High-speed light focusing by scattering medium by cooperatively accelerated genetic algorithm. Authors: Shu Guo. Code, data, media. Code, Data and Media Associated: The focusing of light by randomly scattering materials using wavefront shaping is studied in detail. We propose a newfangled approach, namely a four-element division algorithm, to improve the average convergence speed and the signal-to-noise ratio of focusing. independently controlled light segments, the intensity at, The SAA developed for focusing through scattering media by generating an initial phase mask.
