Imaging With Nature: Compressive Imaging Using a Multiply Scattering Medium

Abstract: The recent theory of compressive sensing leverages upon the structure of signals to acquire them with much fewer measurements than was previously thought necessary, and certainly well below the traditional Nyquist-Shannon sampling rate. However, most implementations developed to take advantage of this framework revolve around controlling the measurements with carefully engineered material or acquisition sequences. Instead, we use the natural randomness of wave propagation through multiply scattering media as a… Show more

“…One way to address such an issue resides in placing a scattering or heterogeneous medium in front of the US probe. This principle has been recently developed in optics and gives promising results [51]. However, such a new design raises many questions regarding the choice and the modelling of the heterogeneous medium.…”

“…On a different scale, optical microscopy demands the ability to reach large depths, in particular when dealing with intra-vital microscopy 17 . Similarly, the physics of optics in random media 3,18,19 , and the attempts to improve focusing through scattering media need to model the depth profile of re-emitted photons [20][21][22][23] . The penetration depth of photons migrating in random media has been studied by several research groups [24][25][26][27][28][29][30][31][32][33][34][35][36][37] .…”

“…In this paper, we circumvent one major limitation of the previous proof-of-concept system [12]. Since optical sensors (here, a CCD camera) only measure the field intensity |y| 2 , in [12] the input image is phase-modulated using a phase-only SLM, with relative phases 0, π/4, π/2, and 3π/4.…”
