Figure 2. Experimental setup for compressive imaging using multiply scattering medium.

Within the imaging device, waves coming from the object (i) go through a scattering material (ii) that efficiently multiplexes the information to all M sensors (iii). Provided the transmission matrix of the material has been estimated beforehand, reconstruction can be performed using only a limited number of sensors, potentially much lower than without the scattering material. In our optical scenario, the light coming from the object is displayed using a spatial light modulator.
