Constructing Large Transmission Matrix of Scattering Sample Based on Super-Resolution Algorithm

A method to construct a large transmission matrix (TM) of highly scattering media based on an algorithm is presented. For imaging through media, measuring TM enables image reconstruction with high spatial resolution; however, it difficult operate in practice because the time required for calibration proportional number calibrated input modes. Instead directly achieving using advanced hardware, defined and constructed multiframe super-resolution algorithm, which traditionally aims recover high-resolution (HR) original object from several low-resolution images. With sufficient size improvement, naturally measured complementary small TMs, each them subpixel-shifted projector phase mask. The realized TM, subpixel registration interpolation operations at help hypothetical HR mask, object’s speckle signal. feasibility proposed proven via optical experiments involving statistical analysis reconstruction. benefits existing TM-based applications offers new perspective measurements resolution.
