Self-imaging in white-light/single-wavelength speckles. (a) Raw speckle captured using broadband white light LED source. (b-c) Experimental results of imaging of different objects (b) digit ‘2’, and (c) digit ‘3’, through thin diffuser with narrow-band filter for high-contrast speckles. The ground truth object is shown in the bottom-left corner. Clearer view and abundant self-imaging units in speckle are directly observed by the naked eye, with no filtering pre-processing or post-processing utilizing computational reconstruction
