  • Publication number: 20170299700
    Abstract: An apparatus and method are used for three-dimensional sensing with a time-of-flight lidar sensor having a single emitter sensing in one dimension, at least one photodetector, and a mechanical means of scanning in two dimensions said emitter and at least one photodetector. The external case of the lidar is preferably static, and only internal components involve mechanical motion. In a preferred embodiment of said lidar when operated in the infrared, said external static case has a window that is visually opaque and essentially transparent to infrared radiation.

  • Publication number: 20160161600
    Abstract: 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.

  • Publication number: 20160047901
    Abstract: An apparatus and method are used for real-time wide-field-of-view ranging with a time-of-flight lidar sensor having one or a plurality of laser emitters and one or a plurality of photodetectors. When a plurarity of laser emitters are used, they are preferably copackaged or are in the form of an integrated multi-emitter chip or emitting multi-chip module in a single package, and when a plurarity of photoreceivers are used, they are preferably copackaged or are in the form of an integrated multi-photoreceiver chip or photoreceiving multi-chip module in a single package. Furthermore, the apparatus comprises any combination of (a) no moving external parts in contact with the environment, (b) wireless energy and data transfer between the static and the moving parts of the lidar, and (c) protective body, sealant and/or damage-resistant tamper-resistant theft-resistant cage.

  • Publication number: 20150293224
    Abstract: 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.

  • Publication number: 20150192677
    Abstract: A three-dimensional mapping system comprising a moderate number (typically 2 to 4) of moderate-beam-count (typically 8-beam to 16-beam) lidar sensors is proposed to achieve low cost systems with wide fields of view. Secondary advantages include compact sensors and a small minimum range (possible by optimal placement of each of a plurality of sensors).

  • Publication number: 20140211194
    Abstract: A lidar-based apparatus and method are used for multi-signal detection, weak signal detection and signal disambiguation through waveform approximation utilizing a multi-channel time-to-digital converter (TDC) electronic circuit, with each TDC having an individually adjustable voltage threshold. This advanced TDC-based pulse width time-of-flight (ToF) approach achieves the low cost associated with the TDC-based pulse width ToF approach while solving the signal quality issues associated with the standard single-threshold TDC-based approach.
