摘要： A distance measurement device includes a light source that emits scanning light, a light receiving sensor that receives returning light, an incidence and emission window that has an annular shape centered at a reference axis set in advance and that is capable of omnidirectionally emitting the scanning light about the reference axis and capable of receiving the incident returning light, a light deflector that includes a movable mirror portion which reflects the scanning light from the light source toward the incidence and emission window and which reflects the returning light from the incidence and emission window toward the light receiving sensor, and that changes a direction of the scanning light by changing a posture of a movable reflection surface, and a relay optical system that relays the scanning light and the returning light between the movable mirror portion and each of the light source and the light receiving sensor.

摘要： A LIDAR system includes a LIDAR chip configured to output a LIDAR output signal. The LIDAR chip includes a waveguide array. A steering mechanism is configured to control a direction that a system output signal travels away from the LIDAR system. The system output signal includes light from the LIDAR output signal. A location that a comparative signal is incident on the waveguide array changes in response to the steering mechanism changing a direction that the system output signal travels away from the LIDAR system. The comparative signal includes light from the system output signal after the system output signal has been reflected by an object located outside of the LIDAR system.

摘要： A receiving device for an optical detection appliance for receiving optical reception signals, in particular of a transmitting device of the detection appliance, that are reflected at an object (18), a detection appliance and a driver assistance system are described. The receiving device comprises at least one optical sensor (36) comprising at least one detection surface (38) with at least one row (44) with a number of optical detection regions (40, 42) extending along a first extension direction (46) of the at least one detection surface (38). At least two of the detection regions (40, 42) can be analysed separately from each other for positional resolution of a received signal. The respective extents of at least two detection regions (40, 42) are different, at least when viewed along the first extension direction (46).

摘要： An eye tracking device for integrating in a frame for mounting to a user's head includes a laser output unit for fixing to the frame. The laser output unit is configured to provide a laser beam for illuminating a cornea of the user's eye when in use. The eye tracking device also includes a receiver unit for fixing to the frame. The receiver unit is configured to receive a reflection of the laser beam and to provide a tracking signal usable for determining a distance or velocity of the cornea.

摘要： The present disclosure is directed to imaging LiDARs with separate transmit (Tx) and receive (Rx) optical antennas fed by different optical waveguides. This pair of optical antennas can be activated at the same time through a dual-channel optical switch network, with the Tx antenna connected to a laser source and the Rx antenna connected to a receiver. The Tx and Rx antennas can be positioned adjacent to each other, so they point to approximately the same far-field angle. No optical alignment between the Tx and Rx is necessary. This LiDAR configuration, referred to herein as pseudo-monostatic LiDAR, eliminates spurious reflections and increases the dynamic range of the LiDAR.

摘要： An electromagnetic wave transmissive cover is configured to be employed in a vehicle equipped with a sensor device. The sensor device is configured to transmit an electromagnetic wave in a transmission direction. The sensor device is arranged in a front end or a rear end of a roof of the vehicle. One of the front end and the rear end in which the sensor device is arranged includes an inclined surface. The inclined surface includes an opening. The electromagnetic wave transmissive cover includes a cover body arranged to close the opening of the inclined surface. The cover body extends along the inclined surface and is inclined with respect to the transmission direction. An anti-reflective portion is arranged on at least one of two surfaces of the cover body in the transmission direction to reduce reflection of the electromagnetic wave.

摘要： A method for steering a beam is disclosed. According to the method, a scene is scanned with a surface emitting grating optically coupled to a free propagation region. The free propagation region is optically coupled to waveguides. The waveguides are disposed at different angles to the surface emitting grating. The scanning includes scanning in a first dimension by cycling through a cross connect to illuminate each waveguide of the waveguides. Scanning in a second dimension is performed by tuning a wavelength of light used to illuminate the waveguides.

摘要： A LIDAR system includes a transmitter unit constructed and arranged to generate light and a photodetector structure for detecting received, reflected light. An actively tunable narrow band optical filter structure is located upstream of the photodetector structure to filter out wavelengths of light associated with sunlight prior to being received by the photodetector structure. The filter structure is constructed and arranged to change optical filtering thereof so as to change wavelengths of light permitted to pass there-through. A photodiode detects light passing through the filter structure. A control unit is associated with the photodiode and the filter structure and is constructed and arranged such that based on the light detected by the photodiode, the control unit can cause the filter structure to change the optical filtering thereof by heating or rotating the filter structure so as to compensate for drifting or broadening of a wavelength of the transmitter unit.
