This review article aims to address common research questions in passive polarized vision for robotics. What kind of polarization sensing can we embed into robots? Can we find our geolocation and true north heading by detecting light scattering from the sky as animals do? How should polarization images be related to the physical properties of reflecting surfaces in the context of scene understanding? This review article is divided into three main sections to address these questions, as well as to assist roboticists in identifying future directions in passive polarized vision for robotics. After an introduction, three key interconnected areas will be covered in the following sections: embedded polarization imaging; polarized vision for robotics navigation; and polarized vision for scene understanding. We will then discuss how polarized vision, a type of vision commonly used in the animal kingdom, should be implemented in robotics; this type of vision has not yet been exploited in robotics service. Passive polarized vision could be a supplemental perceptive modality of localization techniques to complement and reinforce more conventional ones.

“…Solid rocket plume is an important phenomenon existing in the atmosphere, and the research on the radiation phenomenon of rocket plume is of great value in the fields of combustion diagnosis [1] , atmospheric remote sensing [2] , detection and identification [3] . As a basic optical parameter, polarization can expand the traditional spectral imaging information dimension from three dimensions to seven dimensions, greatly enriching the level of information obtained [4] . In the traditional experimental research and simulation of plume radiation phenomenon, the main concern is the spectral intensity information of plume radiation [5] .…”

With the improvement of stealth and penetration ability of high-speed targets, it is more and more difficult to capture and recognize high-speed targets by relying on traditional optical characteristic signals. It is urgent to expand the characteristic optical elements as an effective complement to the existing detection means. As an optical element, polarization greatly expands the optical information dimension and has high application value in the field of target detection and recognition. This paper presents a method for calculating polarization radiation transmission of rocket plume based on Monte Carlo method. The correctness of the algorithm is verified by an example of L13. The detection wavelength of 1.55 um was selected, and the polarization characteristics of the solid rocket plume at different viewing angles and the imaging characteristics at different viewing angles were calculated using this method. The imaging results show that the characteristics of the polarization degree can reflect the profile of the plume at different observation angles. The point source results show that the polarization degree of the plume is very small in the case of point source radiation, and the polarization Angle changes obviously with the change of the relative detection azimuth, which is helpful to analyze the plume orientation and other information in the case of point source detection.

“…[6][7] Especially, owing to their unique physical properties (superconductivity, nonlinear optics, low contact resistance, and intrinsic magnetism), 2D metallic or semimetallic TMDs materials grab considerable attention and show potential applications in 2D electrodes, spintronics, electrocatalysis, and electronic and optoelectronics, etc. [8][9][10][11][12][13][14][15][16] Impressively, 2D metallic or semimetallic-based photodetectors display unique performance in ultrawide band detection, fast response speed, and self-driven operation, owing to the unique energyband structure and Dirac structural characteristics of 2D metal/ semimetals. [17] For instance, the self-powered photodetector based on T d -MoTe 2 shows a broadband photoresponse from 532 nm to 10.6 µm with the responsivity (R) and specific detectivity (D*) of several mA W −1 and 10 6 -10 8 Jones, respectively.…”
