Abstract: The present disclosure describes a system and method for encoding pulses of light for LiDAR scanning. The system includes a sequence generator, a light source, a modulator, a light detector, a correlator, and a microprocessor. The sequence generator generates a sequence code that the modulator encodes into a pulse of light from the light source. The encoded pulse of light illuminates a surface of an object, in which scattered light from the encoded light pulse is detected. The correlator correlates the scattered light with the sequence code that outputs a peak value associated with a time that the pulse of light is received. The microprocessor is configured to determine a time difference between transmission and reception of the pulse of light based on whether the amplitude of the peak exceeds the threshold value. The microprocessor calculates a distance to the surface of the object based on the time difference.

Abstract: A method for evaluating sensor data. Raw sensor data and/or processed sensor data are initially read in from an acceleration sensor and a rotation rate sensor. Measured data are subsequently ascertained from the raw sensor data and/or the processed sensor data. In addition, at least one application criterion is ascertained. The measured data are then corrected based on a mathematical model. In the correction, an angle between a direction of a sensor orientation and a motion direction is maximally changed by a predefined value per time unit when the application criterion is met. The corrected measured data are subsequently output.

Abstract: LiDAR system and methods discussed herein use a dispersion element or optic that has a refraction gradient that causes a light pulse to be redirected to a particular angle based on its wavelength. The dispersion element can be used to control a scanning path for light pulses being projected as part of the LiDAR's field of view. The dispersion element enables redirection of light pulses without requiring the physical movement of a medium such as mirror or other reflective surface, and in effect further enables at least portion of the LiDAR's field of view to be managed through solid state control. The solid state control can be performed by selectively adjusting the wavelength of the light pulses to control their projection along the scanning path.
