摘要： A receiver for a light detection and range finding system is disclosed. The receiver can include an optoelectrical device to receive a pulse of light reflected from a target and to convert the pulse of light to a current pulse. The receiver can also include a transimpedance amplifier (TIA) to convert the current pulse to a voltage pulse. The receiver can also include a tunable filter that has an input coupled to an output of the TIA. The tunable filter can have a frequency response that is adjustable. The TIA and the tunable filter can be disposed on a single integrated circuit (IC) die.

摘要： A measuring device (200) is a device disposed in a mobile body, and includes a measurement unit (202) that scans an object by emitting electromagnetic waves. The measurement unit (202) is controlled by a measurement unit control device (203) including a control unit (204). The control unit (204) sets a scanning range of the measurement unit (202) using information on a position that is a predetermined distance ahead. Specifically, the control unit (204) determines a position that is a predetermined distance ahead of the current position of the mobile body (240), on a predicted course of the mobile body (240). Further, the control unit (204) uses information on the position that is a predetermined distance ahead to set the scanning range of the measurement unit (202).

摘要： A method for processing point clouds having variable spatial distributions of scan lines includes receiving a point cloud frame generated by a sensor configured to sense a vehicle environment. Each of the points in the frame has associated two-dimensional coordinates and an associated parameter value. The method also includes generating a normalized point cloud frame by adding interpolated points not present in the received frame, at least by, for each interpolated point, identifying one or more neighboring points having associated two-dimensional coordinates that are within a threshold distance of two-dimensional coordinates for the interpolated point, and calculating an estimated parameter value of the interpolated point using, for each of the identified neighboring points, a distance between the two-dimensional coordinates and the parameter value associated with the identified neighboring point. The method also includes generating, using the normalized point cloud frame, signals descriptive of a current state of the vehicle environment.

摘要： The present disclosure provides a mobile machine including a laser diode based lighting system having an integrated package holding at least a gallium and nitrogen containing laser diode and a wavelength conversion member. The gallium and nitrogen containing laser diode is configured to emit a first laser beam with a first peak wavelength. The wavelength conversion member is configured to receive at least partially the first laser beam with the first peak wavelength to excite an emission with a second peak wavelength that is longer than the first peak wavelength and to generate the white light mixed with the second peak wavelength and the first peak wavelength. The mobile machine further includes a light detection and ranging (LIDAR) system configured to generate a second laser beam and manipulate the second laser beam to sense a spatial map of target objects in a remote distance.

摘要： A lidar system comprises a light source to emit pulses of light, a scanner, a receiver, and a controller. The scanner includes a rotatable polygon mirror with reflective surfaces, the reflective surfaces being angularly offset from one another along a periphery of the block. The scanner further includes a polygon mirror axle extending into the block, about which the block rotates, a rotary encoder having a rotational component with an axis of rotation aligned with the polygon mirror axle, the rotational component having one or more characteristics configured to cause the rotary encoder to return a signal, and a second mirror pivotable along an axis orthogonal to the polygon mirror axle. The controller is configured to determine a rotational parameter of the polygon mirror in response to the signal returned from the rotary encoder.
