Abstract: A multiview campfire display includes a light source configured to emit a light beam and a spatial light modulator (SLM) positioned to receive the light beam emitted by the light source. The holographic display also includes a user tracker configured to track the head and eyes of the vehicle occupants. The display also includes a controller in communication with the user tracker, the light source, and the SLM. The controller is programmed to receive a eye-tracking signal from the user tracker and control a polarization optics of the light beam emitted by the light source and modulated by the SLM to reroute the image encoded by the SLM for the plurality of vehicle occupants based on the eye-tracking signal, thereby allowing each of the plurality of vehicle occupants to view the image.

Abstract: An optical arrangement includes at least one pair of displays, each pair having a first display and a second display configured to generate light in a visible spectral range. For each pair of displays, the optical arrangement includes a first polarizer configured to polarize the light incident from the first display, a second polarizer configured to polarize the light incident from the second display. The optical arrangement also includes first and second polarizing beam splitters for each pair of displays. Each polarizing beam splitter is configured to receive the polarized light from the first and second polarizers. Each polarizing beam splitter is also configured to reflect one of an s-polarized component and a p-polarized component of the received polarized light into at least one field of view (FOV) and transmit the other of the s-polarized component and the p-polarized component of the received polarized light into the subject FOV(s).

Abstract: A system for indicating an operating mode of a motor vehicle having a vehicle interior and an operator seat arranged therein includes a rotatable steering wheel arranged inside the vehicle interior relative to the operator seat. The steering wheel includes a front side facing the operator seat and an opposing back side. The system additionally includes a light source configured to project a beam of light onto the back side of the steering wheel. The back side of the steering wheel is configured to capture the light beam and illuminate therewith the front side of the steering wheel to thereby generate a sensory signal indicative of the operating mode to a vehicle operator positioned in the operator seat. A motor vehicle employing the system for generating a sensory signal to a vehicle operator for indicating an operating mode of the vehicle is also disclosed.

Abstract: A vehicle and/or a method for detecting contaminants on an optical surface are provided. The vehicle includes at least one light source adjacent the optical surface and at least one light detector at an edge of the optical surface. A controller is configured to introduce light from at least one light source into the optical surface, and to measure light at the edge of the optical surface with at least one detector. The controller compares the measured light to a threshold, and, if the measured light crosses the threshold, triggers or implements a response action.

Abstract: Systems and methods in a vehicle involve transmitting light with an initial polarization from a lidar system, and controlling an external compensator, external to the lidar system, or an internal compensator within the lidar system to change the initial polarization of the light to a new polarization of the light. The method also includes receiving reflected light resulting from reflection of the light from one or more objects, and obtaining information about the one or more objects based on the reflected light.

Abstract: A method for measuring a distance to a target based upon time modulated polarization state illumination is provided. The method includes: transmitting a time varying polarized light beam toward the target; capturing, at a plurality of sub pixel regions of a receiver, a reflected time varying polarized light beam that has been reflected off of the target; generating a plurality of polarization signals for each sub pixel region that are indicative of the polarization state of the captured reflected light beam in the sub pixel region; calculating a time difference between the transmitted time varying polarized light beam and the captured reflected light beam by comparing the polarization state of the captured reflected light beam with a polarization state of the transmitted time varying polarized light beam; and calculating the distance by multiplying the calculated time difference with the speed of light.

Abstract: A system and method for obtaining an overall image that is constructed from multiple sub-images. The method includes: capturing a first sub-image having a first sub-image field of view using an image sensor of an electronically-steerable optical sensor; after capturing the first sub-image, steering light received at the electronically-steerable optical sensor using an electronically-controllable light-steering mechanism of the electronically-steerable optical sensor so as to obtain a second sub-image field of view; capturing a second sub-image having the second sub-image field of view using the image sensor of the electronically-steerable optical sensor; and combining the first sub-image and the second sub-image so as to obtain the overall image.

Abstract: A scanning and perception system for a vehicle camera having an instantaneous field of view (iFOV) and configured to capture an image of an object at a saturation level in the camera's iFOV. The system also includes a light source configured to illuminate the camera's iFOV. The system additionally includes a radar configured to determine the object's velocity and the object's distance from the vehicle, and a mechanism configured to steer the radar and/or the camera. The system also includes an electronic controller programmed to regulate the mechanism and adjust illumination intensity of the light source in response to the saturation level in the image or the determined distance to the object. The controller is also programmed to merge data indicative of the captured image and data indicative of the determined position of the object and classify the object and identify the object's position in response to the merged data.
