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 1500×1240 pixels in the spatial domain, 19 wavelength channels between 400 and 680 nm and two Stokes parameters.
我们描述了一种单次偏振光谱成像仪,它将两个双折射晶体与一个二进制编码孔径相结合,以对空间、光谱和偏振数据立方体进行编码,以便在二维(2D)探测器阵列上进行压缩采样。我们使用总变差先验从单个2D测量中重建四维(4D)数据立方体。该4D数据立方体在空间域中包括1500×1240像素,在400至680nm之间有19个波长通道以及两个斯托克斯参数。
