Abstract
(EN)
A laser radar, comprising: a laser (10): used for emitting a laser light beam; a probe (20): used for receiving the reflected laser light beam; and a set of transceiver structures (30): used for receiving the laser light beam emitted along a preset direction and conveying the laser light beam to the probe (20), the transceiver structures (30) being arranged coaxially with the laser (10), the transceiver structures (30) comprising a vertical field of view adjustment unit, and the vertical field of view adjustment unit making the laser light beam have a non-uniform distribution in the vertical field of view range and/or adjusting the vertical field of view range of the laser light beam. The laser radar has a simple structure and is convenient to assemble and, when in use, can more flexibly make adjustments for a probe target (40) by means of the laser (10) and the vertical field of view adjustment unit, effectively preventing waste.

L'invention concerne un radar laser, comprenant : un laser (10) utilisé pour émettre un faisceau de lumière laser ; une sonde (20) utilisée pour recevoir le faisceau de lumière laser réfléchi ; et un ensemble de structures d'émetteur-récepteur (30) utilisé pour recevoir le faisceau de lumière laser émis le long d'une direction prédéfinie et acheminer le faisceau de lumière laser vers la sonde (20), les structures d'émetteur-récepteur (30) étant agencées de manière coaxiale avec le laser (10), les structures d'émetteur-récepteur (30) comprenant une unité de réglage de champ de vision vertical, et l'unité de réglage de champ de vision vertical amenant le faisceau de lumière laser à avoir une distribution non uniforme dans la plage de champ de vision vertical et/ou à régler la plage de champ de vision vertical du faisceau de lumière laser. Le radar laser a une structure simple et est pratique à assembler et, lorsqu'il est utilisé, peut effectuer des réglages de manière plus flexible pour une cible de sonde (40) au moyen du laser (10) et de l'unité de réglage de champ de vision vertical, ce qui évite efficacement le gaspillage.

一种激光雷达,包括:一个激光器(10):用于发射激光光束;一个探测器(20):用于接收反射回来的激光光束;一组收发结构(30):用于接收沿着预设方向射出的激光光束、并将激光光束传递给探测器(20),收发结构(30)与激光器(10)同轴设置,收发结构(30)包括一垂直视场调节单元,垂直视场调节单元使得激光光束在垂直视场范围内呈非均匀分布和或调节激光光束的垂直视场范围。激光雷达的结构更简单,装配起来方便。在使用时能够比较灵活的针对探测目标(40)进行通过激光器(10)和垂直视场调节单元来调节,可以有效地避免浪费。
