Speckle-based 3D sub-diffraction imaging of sparse samples through a multimode fiber
A flexible multimode fiber is an exceptionally efficient tool for in vivo deep tissue imaging.Recent advances in compressive multimode fiber sensing allow for imaging with sub-diffraction ULTRA PROBIOTIC spatial resolution and sub-Nyquist speed.At present, the technology is limited to imaging in a two-dimensional (2D) plane near the fiber distal fa
