摘要： In one embodiment, a ladar system includes a laser transmitter with at least one semiconductor laser having a pulsed laser light output. A laser drive circuit is connected to said at least one semiconductor laser and adapted to electrically drive said at least one semiconductor laser in a predetermined sequence. A laser beam steering mechanism is adapted to scan the pulsed laser light output sequentially through the field of view. A two-dimensional array of light sensitive detectors receive reflected light and an integrated circuit calculates a direct time of flight distance measurement.

摘要： A vehicle and ladar sensor assembly system is proposed which makes use of forward mounted long range ladar sensors and short range ladar sensors mounted in auxiliary lamps to identify obstacles and to identify potential collisions with the vehicle. A low cost assembly is developed which can be easily mounted within a body panel cutout of a vehicle, and which connects to the vehicle electrical and computer systems through the vehicle wiring harness. The vehicle has a digital processor which interprets 3D data received from the ladar sensor assembly, and which is in control of the vehicle subsystems for steering, braking, acceleration, and suspension. The digital processor onboard the vehicle makes use of the 3D data and the vehicle control subsystems to avoid collisions and steer a best path.
