Title
(EN) Laser radar system and lighting device thereof
(ZH) 激光雷达系统及其照明装置
Abstract
(EN)
The utility model discloses a laser radar system and lighting device thereof. Wherein, a laser radar lighting device is including near field lighting mechanism, far field lighting mechanism to and beused for producing near field control impuls and far field control impuls's controller, near field lighting mechanism all is the frame illumination light nearest apart from this reverberation receiving time according to near field control impuls output near field illumination light, the arbitrary reverberation of laser radar received, according to the output of this illumination light constantly,can confirm flight time of the affiliated illumination light of this reverberation, far field lighting mechanism's output sets up with near field lighting mechanism's output side by side. Realized awaiting measuring under the distance information's of object the prerequisite acquireing the far field within range, acquireed the distance information's of the object that awaits measuring of near field within range quick travel technological effect in real time.
