Abstract: An apparatus in the field of optics technology, can include a reflector, a reflector substrate, and an extinction component. The reflector can be mounted on the reflector substrate. The extinction component can be arranged on a front surface of the reflector substrate. The reflector can be configured to reflect incident light signals.

Abstract: The present disclosure provides, for example, a lidar ranging method. The method may include calling a sequencer to generate a preset sequence with the sequencer. The method may also include determining a pulse transmission interval of double pulses according to the preset sequence and a preset value. The method may further include transmitting a probing signal to an object to be ranged according to the pulse transmission interval of the double pulses. The method may additionally include receiving, from the object to be ranged, an echo signal returned according to the probing signal. The method may also include extracting a valid echo signal from the echo signal. The method may further include calculating a distance from the object to be ranged according to a time difference between the valid echo signal and the probing signal.

Abstract: A lidar, and an anti-interference method therefor, may modulate a transmitting time of the lidar by injecting random time jitter at a time interval in a sequence of the transmitting time, and cause the lidar to transmit a laser pulse according to a modulated transmitting time. When an echo received by the lidar includes an expected echo of the local lidar and an unexpected echo from other lidars, because the transmitting time and the expected receiving time of the echo are correlated, injecting random time jitter in the transmitting time of the lidar may disrupt the correlation between the transmitting time of the local lidar and the transmitting time of other lidars. Thus, when a plurality of lasers are used together in one scenario and cause crosstalk, the anti-interference method for the lidar above can be used to fight against crosstalk to some extent.
