The present technology relates to an imaging system and an imaging device that enable imaging at an appropriate angle of view while preventing reflection, in a case where imaging of the surroundings of a vehicle is performed from inside the vehicle. An imaging system includes an imaging device that includes a plurality of pixels that receives incident light entering from an object after passing through neither an imaging lens nor a pinhole and each outputs a detection signal indicating an output pixel value modulated in accordance with the incident angle of the incident light, the imaging device being mounted so that the light receiving surface faces the surface of a windshield on the inner side of a vehicle and is in contact with or in proximity to the surface of the windshield. In this imaging system, the average of the centroids of incident angle directivities indicating the directivities of the plurality of pixels with respect to the incident angle of the incident light is biased in one direction from the center of the pixel. The present technology can be applied to an in-vehicle system, for example.

Systems, assemblies, and methods for detecting changes in polarization states are described. Example systems may include a light receiving unit including a sensor and a receiving polarizer. The sensor is configured to sense light from a polarized light source deflected through the receiving polarizer by a light directing article. The sensor is configured to generate a signal indicative a received polarization state of light deflected by the light directing articles. Such systems may be coupled to vehicles and may be useful for sensor-detectable signs, indicia, and markings to facilitate automated or assisted vehicular transport.
