Mathematica(@mathemetica):Classical vs. Advanced Sampling Techniques (a) Classical Nyquist-Shannon sampling: Requires a full array of M=N sensors to capture the object at the Nyquist rate. (b) Single-pixel camera: Uses an array of reflectors (modulators) with only M=1 sensor. (c) Multiply scattering imager: Employs scattering media with fewer sensors (M < N). Visualizing how compressive and computational imaging can reduce hardware requirements while reconstructing the original object.
