摘要：

We describe a single-shot polarization spectral imager that combines two birefringent crystals with a binary coded aperture to encode the spatial, spectral and polarization data cube for compressive sampling on a two-dimensional (2D) detector array. We use a total variation prior to reconstruct the four-dimensional (4D) data cube from the single 2D measurement. The 4D data cube includes 1500 x 1240 pixels in the spatial domain, 19 wavelength channels between 400 and 680 nm and two Stokes parameters. (C) 2013 Optical Society of America
