    Abstract: A distance measurement apparatus (10) is an apparatus that emits light through a transmissive member (20) and detects reflection light from a target object. The distance measurement apparatus (10) includes a light receiving unit (180) and a switching control unit (121). The light receiving unit (180) receives internal reflection light including reflection light reflected by the transmissive member (20) and the reflection light from the target object. The switching control unit (121) switches a detection process on the reflection light from the target object by using a light reception result of the internal reflection light by the light receiving unit (180).

    Abstract: Systems and methods are provided. One aspect of the present invention relates to an autonomous vehicle (AV) system configured to control a vehicle, the AV system comprising: a Lidar unit to provide ranging information for the vehicle, the Lidar unit to emit light signals into a surrounding environment and to receive return signals corresponding to reflections of the light signals off the surrounding environment; a noise source detector configured to detect a noise signal producing noise in one or more return signals being received by the Lidar unit; a noise processing system configured to detect a noise source corresponding to the noise signal, wherein the detecting of the noise source comprising: determining a direction of the noise source relative to the vehicle; and determining a classification of the noise source based on an intensity of the noise signal. The AV system further comprises a perception system configured to generate state data to describe the noise source, the state data including the direction of the noise source relative to the vehicle and the classification of the noise source; and a vehicle controller configured to control one or more operations of the vehicle based on the state data that describes the noise source.

    Abstract: The disclosure relates to the technical field of lidar, and specifically provides a human eye protection circuit, a control method therefor, an electronic device, a medium, and a vehicle, to resolve the problem of damage to human eyes caused by continuous emissions from a mechanical rotary vehicle-mounted lidar to a fixed object. For this purpose, the human eye protection circuit in the disclosure includes a comparator circuit (101) and a control circuit (102). The comparator circuit includes at least a first comparator (U1) and a second comparator (U2), an output terminal of the first comparator is connected to an input terminal of the second comparator, and the comparator circuit is configured to output a level signal to the control circuit based on a rotation situation of the rotating mirror motor. The control circuit includes at least one logic gate (U3), and the control circuit is configured to: receive the level signal output by the comparator circuit, and output a laser control signal to control whether the laser works. In this way, whether the laser works is automatically controlled based on the rotation situation of the rotating mirror motor (M), to prevent damage to human eyes caused by continuous emissions to a fixed object.

    Abstract: Um eine einfache und präzise Justage eines optischen Elements (3) gegenüber einer Lichtsende- (4) oder Lichtempfangseinheit (5) eines optoelektronischen Sensors (S) zu gewährleisten, werden eine Justage-Vorrichtung (1) und ein Justage-Verfahren bereitgestellt, wobei das optische Element (3) in einem zylindrischen Optikträger (2) gelagert ist und die Lichtsende- (4) bzw. Lichtempfangseinheit (5) auf einer Elektronikkarte (6) des Sensors (S) angeordnet ist, und wobei die Justage-Vorrichtung (1) derart ausgebildet ist, dass der Optikträger (2) ortsfest in einer definierten Position relativ zu der Lichtsende- (4) bzw. Lichtempfangseinheit (5) anordenbar ist, und dass Druckluft (DI) in den Optikträger (2) einleitbar ist, um das in dem Optikträger (2) vorgesehene optische Element (3) in Richtung eines ersten und eines zweiten Freiheitsgrads (x und y) innerhalb des Optikträgers (2) quer zu einer Längsachse (L) zu fixieren und um das optische Element (3) in Richtung der Längsachse (L) in eine definierte Betriebsposition zu bewegen, wobei ein berührungsloses Bewegen des optischen Elements (3) entlang der Längsachse (L) des Optikträgers (2) zu der Lichtsende- (4) bzw. Lichtempfangseinheit (5) hin oder von der Lichtsende- (4) bzw. Lichtempfangseinheit (5) weg ausführbar ist, so dass das optische Element (3) gegenüber der Lichtsende- (4) bzw. Lichtempfangseinheit (5) in die definierte Betriebsposition ausrichtbar und in der Betriebsposition befestigbar ist, in der das optische Element (3) gegenüber der Lichtsende- (4) bzw. Lichtempfangseinheit (5) justiert ist.
