Abstract: Systems and methods to perform sensor fusion with a depth imager and a radar system involve transmitting radio frequency (RF) energy from the radar system to a region and simultaneously emitting light to the region using a light source, Reflected light is received at a depth imager aligned with the light source, and RF reflections are received at the radar system. The reflected light is processed to obtain azimuth, elevation, range, variance in range, and reflectivity to each pixel that makes up the region. Processing the RF reflections provides azimuth, elevation, range, variance in range, velocity, and variance in velocity to a subset of the pixels representing a region of interest. Performing the sensor fusion includes using the azimuth, the elevation, the variance in range, and the reflectivity resulting from the depth imager and the range, the velocity, and the variance in velocity resulting from the radar system.

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 depth imaging system in a vehicle includes a lens that includes a polarization-coded aperture. The polarization-coded aperture includes a perpendicular polarization portion to pass incident light entering the perpendicular polarization portion of the polarization-coded aperture as perpendicularly polarized light. The polarization-coded aperture also includes a parallel polarization portion to pass the incident light entering the parallel polarization portion of the polarization-coded aperture as parallel polarized light. An image sensor provides a perpendicularly polarized image based on the perpendicularly polarized light and a parallel polarized image based on the parallel polarized light. A controller processes the perpendicularly polarized image and the parallel polarized image to identify one or more objects in a field of view of the depth imaging system and to determine a range to each of the one or more objects.

Abstract: A vehicle, imaging system and method of determining a range of an object to a vehicle. The imaging system includes a light source, a receiver and a processor. The light source is configured to transmit a source signal at a source frequency at an object, wherein the source signal is reflected from the object to create a reflected signal. The receiver includes a sensor array and is configured to modulate the reflected signal at a mixing frequency to generate a down-converted signal and record the down-converted signal at the sensor array. The processor is configured to determine a range of the object to the vehicle using the down-converted signal.
