摘要： A LIDAR system has a beam steerer and a signal director that are each configured to steer within a field of view a system output signal that is output from the LIDAR system. A path of system output signal in the field of view has a contribution from the beam steerer and the signal director. The contribution of the beam steerer to the path is movement of the system output signal on a two-dimensional path back and forth across the field of view. The contribution of the signal director to the path is movement of the system output signal transverse to the two-dimensional path contribution of the provided by the beam steerer.

摘要： A LIDAR system has a switch configured to direct a switch signal to one of multiple different alternate waveguides. The switch signal carries multiple different channels. The system also includes one more redirection components that receive multiple different channel output signals. Each of the channel output signals carries a different one of the channels. The one more redirection components are configured to redirect the channel output signals such that a direction that each of the channel output signals travels away from the one more redirection components changes in response to a change in the alternate waveguide which receives the switch signal.

摘要： A light source has a resonant laser cavity with an optical grating and a waveguide that has a longitudinal axis. A portion of the longitudinal axis extends through the optical grating and serves as a grating axis. The laser cavity is configured to generate a laser signal that exits the laser cavity through the optical grating. The optical grating includes multiple perturbation structures that each causes a perturbation in an effective refractive index of the waveguide. The perturbation structures are staggered on the waveguide such that the perturbation structures that are adjacent to one another in a longitudinal direction are spaced apart in a transverse direction. The longitudinal direction is a direction parallel to the grating axis and the transverse direction is a direction transverse to the longitudinal direction.

摘要： A LIDAR system includes a LIDAR chip that is configured to output a LIDAR output signal such that the LIDAR output signal can be reflected by an object located off the LIDAR chip. The LIDAR chip is also configured to receive a LIDAR input signal that includes light from the reflected LIDAR output signal. The LIDAR chip is configured to combine the LIDAR input signal with a reference signal so as to produce a beating signal. The electronics operate the LIDAR chip such that the effects of radial velocity between the reflecting object are reduced or removed from the beating signal while measuring the distance between the LIDAR chip and the reflecting object. The electronics operate the LIDAR chip such that the effects of the distance between the reflecting object are reduced or removed from the beating signal while measuring the radial velocity between the LIDAR chip and the reflecting object.

摘要： Built-in self-test programmable logic arrays use a deterministic test pattern generator to generate test patterns such that each cross point in an AND-plane can be evaluated sequentially. A multiple input signature register which uses XQ + 1 as its characteristics polynomial is used to evaluate the test results, where Q is the number of outputs. The final signature can be further compressed into only ONE bit. Instead of only determining the probability of fault detection, in this scheme, the fault detection capability has been analyzed using both the stuck at fault and the contact fault model. It can be shown that all of these faults can be detected. Shorts between two adjacent lines can be detected by using NOR gates.

摘要： A LIDAR system has one or more light splitters and multiple light combiners. The LIDAR system also has multiple optical pathways through which light signals travel. The optical pathways include delay pathways that each extends from one of the one or more splitters to one of the light combiners. The optical pathways include expedited pathways that each extends from one of the splitters to one of the light combiners. Each of the light combiners has one of the delay pathways and one of the expedited pathways extending to the light combiner. The delay pathways and the expedited pathways are configured such that the delay pathway to each light combiner is longer than the expedited pathway to the same light combiner.

摘要： A LIDAR system is configured to output a system output signal that travels away from the LIDAR system and can be reflected by objects located outside of the LIDAR system. The system output signal has a frequency versus time pattern with a repeated cycle. Each cycle of the frequency versus time pattern includes multiple data periods configured such that the system output signal is chirped differently in different data periods. The LIDAR system also includes electronics configured to generate multiple different sets of LIDAR data. Each set of LIDAR data indicates a radial velocity and/or separation between the LIDAR system and one or more of the objects located outside of the LIDAR system. Each set of LIDAR data is generated from light that is included in the system output signal during a group of multiple data periods. The groups of data periods including one or more common data periods that are each included in two or more different groups of data periods.
