An apparatus has a collection of emitters on an emitter substrate with irregular distances between the collection of emitters to produce optical beams in a far field with a more even distribution than conventional optical beams in the far field produced by a conventional collection of emitters with regular distances between the conventional collection of emitters. A collection of receivers on a receiver substrate has irregular distances between the collection of receivers. A system substrate hosts the emitter substrate and the receiver substrate.

Non-uniform lidar beam configuration for object detection, tracking and classification

A system has a collection of lidar sensors to generate lidar point cloud data for a defined geolocation. A computer is connected to the collection of lidar sensors via a network. The computer includes a processor and a memory storing instructions executed by the processor to process the lidar point cloud data to produce an object list for each moving object identified in the lidar point cloud data. The object list includes object classification information, object motion information, object position data, and object size data. Object motion analyses are performed on each object list to generate object motion analytics for the defined geolocation.

Apparatus and method for object motion analyses of lidar sensor data

A lidar-based apparatus and method are used for the solid state steering of laser beams using Photonic Integrated Circuits. Integrated optic design and fabrication micro- and nanotechnologies are used for the production of chip-scale optical splitters that distribute an optical signal from a laser essentially uniformly to an array of pixels, said pixels comprising tunable optical delay lines and optical antennas. Said antennas achieve out-of-plane coupling of light. As the delay lines of said antenna-containing pixels in said array are tuned, each antenna emits light of a specific phase to form a desired far-field radiation pattern through interference of these emissions. Said array serves the function of solid state optical phased array. By incorporating a large number of antennas, high-resolution far-field patterns can be achieved by an optical phased array, supporting the radiation pattern beam forming and steering needed in solid state lidar, as well as the generation of arbitrary radiation patterns as needed in three-dimensional holography, optical memory, mode matching for optical space-division multiplexing, free space communications, and biomedical sciences. Whereas imaging from an array is conventionally transmitted through the intensity of the pixels, the optical phased array allows imaging through the control of the optical phase of pixels that receive coherent light waves from a single source.

Solid state optical phased array lidar and method of using same

A lidar-based system and method are used for the solid state beamforming and steering of laser beams using optical phased array (OPA) photonic integrated circuits (PICs) and the detection of laser beams using photodetectors. Transmitter and receiver electronics, power management electronics, control electronics, data conversion electronics and processing electronics are also included in the system and used in the method. Laser pulses beamformed by the OPA PIC reflect from objects in the field of view (FOV) of said OPA, and are detected by a detector or a set of detectors. A lidar system includes at least one lidar, and any subset and any number of complementary sensors, data processing/communication/storage modules, and a balance of system for supplying power, protecting, connecting, and mounting the components of said system. Direct correlation between the 3D point cloud generated by the lidar and the color images captured by an RGB (Red, Green, Blue) video camera can be achieved by using an optical beam splitter that sends optical signals simultaneously to both sensors. A lidar system may contain a plurality of lidar sensors, a lidar sensor may contain a plurality of optical transmitters, and an optical transmitter may contain a plurality of OPA PICs.

In one embodiment of the present invention, a method is provided comprised of creating a plurality of vias on a substrate, the vias formed in material that has a maximum processing temperature that less than a pre-defined threshold; adding a plurality of electrically conductive material into the vias; and solution depositing a nanowires infused window layer that has a first thickness at certain areas and a second thickness at other areas, wherein overall sheet resistance is between about 1 to 10 ohms per square, while light transmission combined is at least 70% and creates less than 5% shadow loss. The method may involve using a transparent conductive oxide layer beneath the window layer. This can create a layer that eliminates opaque bus bars or fingers associated with traditional solar cells. This may be an all-solution deposited process using only one deposition set or multiple deposition steps.
