Innovative 激光雷达技术: Optical Modules 和 Components for LiDAR Sensors

Delivering the Power of 光 – For more efficiency, safety, 和 autonomy.

激光雷达的无人机

LiDAR sensors are a key technology of the future for process automation or highly automated, fully automated 和 autonomous driving. In conjunction with cameras 和 radar sensors, 他们感知周围的环境, 帮助取向, 检测到障碍物, measure distances - 和 thus ensure greater safety 和 efficiency on busy roads 和 in automated industrial environments.

光 Detection And Ranging in 3D: the key to fully autonomous driving

By generating precise 3D images of the vehicle or automation environment through thous和s of distance measurements per second, 3D LiDAR sensors provide essential information for reliable object detection 和 collision avoidance. The optical LiDAR method allows higher spatial 和 depth resolution compared to radar sensors, is faster 和 less computationally intensive than camera technology 和 thus complements the vision of semi-autonomous 和 autonomous vehicles or industrial installations.

Behind the simple-sounding method is high-tech: The exact interaction of laser, optics 和 detector of the transmitting 和 receiving unit of a 3D LiDAR sensor based on Flash, 固态, 微机电系统, or rotating mirror technology requires profound know-how 在se disciplines. 正是这种 combination of knowledge 和 practical experience 这使得 Jenoptik在这一地区是独一无二的.

Overview of common LiDAR measurement methods

The 3D LiDAR method is based on scanning or imaging the environment by means of many individual optical distance measurements (= 光 Detection And Ranging). These distance information is combined into a 3D image (“point cloud”) of the environment seen by the LiDAR sensor. The distance information per image is recorded successively (扫描激光雷达) or simultaneously (non-scanning Flash激光雷达), depending on the LiDAR measurement method.

闪光激光雷达(非扫描激光雷达)

Flash激光雷达 sensors illuminate their field of view by means of a single exp和ed laser pulse or laser beam. The reflected laser light is then imaged on a detector array 和 the time-of-flight for the light per detector element is evaluated. This results in a complete 3D image of the field of view for each single laser pulse emitted. Since Flash-LiDAR sensors do not use any moving parts, 这些传感器很健壮, insensitive to vibrations 和 compact. For example, they can be easily integrated into autonomous vehicles also in large quantities.

扫描激光雷达

扫描激光雷达 sensors scan the environment with many individual laser pulses. 为了这个目的, 一个平行, pulsed laser beam (as a point or line shape) is guided over the field of views by means of a scanning optical system (transmitter optics). The light reflected by the sensor’s environment is then guided to a photodetector (receiver optics). Rotating polygon mirrors or micro-electromechanical systems, 所谓微机电系统, based on semiconductors are used as deflection optics. Disadvantages of these sensors are their bulky size, 运动部件造成的磨损, 还有制造成本.

Components 和 sub-modules for 3D LiDAR sensors

Transmitter Optics for LiDAR Sensors

聚合物客观镜头

发射机光学

The LiDAR sensor’s transmitter optics have the task of shaping (i.e. collimating or exp和ing) the laser beam 和 directing it to the field of view (FOV) of the sensor, 来衡量. 视传感器类型而定, the transmitter optics generate single laser spots, laser lines or illuminate the complete field of view of the sensor. Homogeneity 和 distortion-free imaging are prerequisites for reliable measurement data of the LiDAR sensor.

Our offerings 和 services include:

  • 带反射镜的发射光学装置, 镜头, diffractive or refractive optical elements (DOE, 和微透镜阵列(MLA)
  • 混合的镜头. These combine the best properties of spherical, aspherical 和 free-form optics based on 玻璃 or plastic (polymers, 聚碳酸酯)
  • Athermal 镜头 for temperature ranges from -40 °C to +110 °C
  • Optomechanical design of customer-specific lens systems
  • 成像光学和准直器
  • Structured laser lighting (point, line, area)

Optical Diffusers for Flash激光雷达 Sensors

Diffractive diffusers - absorb a monochromatic laser beam 和 scatter the light into any imaginable pattern

光学扩散器

Flash激光雷达 sensors require homogeneous, full-area illumination of the field of view. 为实现这一目标, the laser beam is exp和ed homogeneously by optical diffusers, 和 then projected onto the field of view (FOV) of the LiDAR sensor. Depending on the measurement geometry 和 sensor type, different diffusers are used for which we can offer you tailor-made solutions.

Your advantage: Our expertise in optical diffusers is as diverse as it is unique. At our locations in 德国 和 the USA, we combine technological know-how, R&D resources 和 various 生产 processes from fast prototyping 和 ultra-precision technology to photolithography 和 two-component injection molding.
