Advanced imaging techniques by compressive sensing

Compressive sensing is an emerging theory that shows a considerable variety of applications in the field of imaging techniques. In particular, a practical challenge addressed by compressive sampling is the design of optical systems able to provide spatial information about specific optical properties of an object. As an example of this kind of advanced imaging techniques, we present an optical architecture that performs spatially resolved measurements of the Stokes parameters of the light coming from a polarization object. To this end, a commercial (single-pixel) polarimeter is used as light detector to perform CS measurements. Experimental results are presented for an object that provides an inhomogeneous polarization distribution.
