Abstract: A windshield corrective optical system includes a motor vehicle having a windshield. A camera is positioned within an occupant compartment of the motor vehicle directed toward the windshield and receiving light rays passing through the windshield. A sensor is configured to receive the light rays. A corrective element is configured to allow passage of the light rays through the corrective element to the sensor. The corrective element corrects aberrations of the light rays induced by passing through the windshield prior to the light rays reaching the sensor.

Abstract: System and method of controlling operation of an optical sensor in a device. The optical sensor is configured to employ a scan pattern to scan respective portions of a full field of view. A navigation sensor is configured to obtain location coordinates of the device. An inertial sensor is configured to obtain an acceleration data of the device in a plurality of directions. A controller is configured to determine a position of the device at the present time based in part on the location coordinates and the acceleration data. The controller is configured to determine a sun striking zone based in part on a relative position of the sun and the device. When a sun overlap region between the respective portions of the full field of view and sun striking zone exceeds a first overlap threshold, operation of the optical sensor is modified.

Abstract: A system to localize debris on an optical surface of a vehicle includes a first array along a first side of a perimeter of the optical surface and including a light source to emit light into a thickness of the optical surface. A second array is along a second side of the perimeter, opposite the first side, and includes a light detector to detect light scatter in the thickness and provide a corresponding output. A third array is along a third side of the perimeter and includes a light source to emit light. A fourth array is along a fourth side of the perimeter, opposite the third side, and includes a light detector to detect light scatter and provide a corresponding output. A controller identifies a presence of the debris, determines a position of the debris based on the output from the light detectors, and remediates the debris.

Abstract: Method and systems for image deblurring in a vehicle. The methods and systems include determining a point spread function based on vehicle motion data and a depth map received from vehicle motion sensors and a depth sensor. A deblur matrix is calculated based on the point spread function. A blurred input image, received from an imaging device, is deblurred based on the deblur matrix to thereby provide a deblurred output image. A function of the vehicle is controlled based on the deblurred output image.

Abstract: A device for imaging a region of interest includes a scanning assembly configured to steer a light beam incident thereon relative to a target location. The scanning assembly includes a first stationary optical device configured to control a circular polarization direction of the light beam and transmit the light beam to a second stationary optical device, and the second stationary optical device is configured to deflect the light beam to the target location. The device also includes an image sensor configured to generate an image based on the deflected light beam.

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: A vehicle, Lidar system and method of imaging a field of interest. A laser illuminates a field of interest with a source pulse of light. A quadrant detector receives a reflected pulse that is a reflection of the source pulse from the field of interest. A processor determine a three-dimensional image of the field of interest from a location of the reflected pulse at the quadrant detector and a time-of-flight for the reflected pulse. The processor further navigates the vehicle through the field of interest using the three-dimension image.

Abstract: A system includes a projector module configured to project a visual media for a user, a user tracking sensor configured to sense whether the user is observing the visual media, and a control module configured to detect whether the user is looking at the projector module based on the user tracking sensor, in response to detecting the user is looking at the projector module, control the projector module to initiate projecting of the visual media for the user, detect an interruption of the user observing the visual media based on the user tracking sensor, and in response to detecting the interruption of the user observing the visual media, control the projector module to pause projecting of the visual media for the user. Other example systems and methods for controlling projection of a visual media for a user in a vehicle are also disclosed.

Abstract: A system and method of classifying an object. The system includes a polarizing beam splitter, a first detector, a second detector and a processor. The polarizing beam splitter generates a first source signal having a first polarization direction and a second source signal having a second polarization. The first detector transmits the first source signal at the object and receives a first reflected signal generated at the object in response to the first source signal. The second detector transmits the second source signal at the object and receives a second reflected signal generated at the object in response to the second source signal. The processor is configured to compare the first reflected signal to the second reflected signal to classify the object.
