“…Recently, there have been increases in the demand for new multimedia resources of three-dimensional content, particularly in images, games, movies and augmented reality. In this context, capturing 3D information or depth sensing is essential for many applications including object and material classification [ 1 , 2 , 3 ], navigation [ 4 , 5 ], image polarization contrast in biological tissues [ 6 , 7 , 8 , 9 ], improved vision in haze conditions [ 10 ] and diagnosis in oncology [ 11 , 12 ], different views of the same image [ 13 , 14 ], facial recognition in the surveillance area [ 15 , 16 , 17 , 18 ], atmospheric remote sensing and other applications. Therefore, the search for improvements in depth sensing and 3D image capture has become an important target in the field of image sensors.…”

Targeting 3D image reconstruction and depth sensing, a desirable feature for complementary metal oxide semiconductor (CMOS) image sensors is the ability to detect local light incident angle and the light polarization. In the last years, advances in the CMOS technologies have enabled dedicated circuits to determine these parameters in an image sensor. However, due to the great number of pixels required in a cluster to enable such functionality, implementing such features in regular CMOS imagers is still not viable. The current state-of-the-art solutions require eight pixels in a cluster to detect local light intensity, incident angle and polarization. The technique to detect local incident angle is widely exploited in the literature, and the authors have shown in previous works that it is possible to perform the job with a cluster of only four pixels. In this work, the authors explore three novelties: a mean to determine three of four Stokes parameters, the new paradigm in polarization cluster-pixel design, and the extended ability to detect both the local light angle and intensity. The features of the proposed pixel cluster are demonstrated through simulation program with integrated circuit emphasis (SPICE) of the regular Quadrature Pixel Cluster and Polarization Pixel Cluster models, the results of which are compliant with experimental results presented in the literature.
