Innovative LiDAR Technologies: Optical Modules and Components for LiDAR Sensors

Delivering the Power of Light – For more efficiency, safety, and autonomy.

LiDAR Drone

LiDAR sensors are a key technology of the future for process automation or highly automated, fully automated and autonomous driving. In conjunction with cameras and radar sensors, they perceive the surroundings, help with orientation, detect obstacles, measure distances - and thus ensure greater safety and efficiency on busy roads and in automated industrial environments.

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

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

Behind the simple-sounding method is high-tech: The exact interaction of laser, optics and detector of the transmitting and receiving unit of a 3D LiDAR sensor based on Flash, solid state, MEMS, or rotating mirror technology requires profound know-how in these disciplines. It is this combination of knowledge and practical experience that makes Jenoptik unique in this area.

As a leading photonic specialist, we enable our customers to create custom LiDAR sensors for challenging applications in the automotive, mobility, industrial automation, and safety & security markets. Our offer ranges from customized optical and opto-electronic components and assemblies for 1D to 3D LiDAR sensors (polygon and MEMS mirror based, Flash LiDAR, etc.) to integrated 1D laser rangefinder and test equipment for all types of LiDAR sensors. Embark on the journey with us and benefit from The Power of Light!

No matter what you call them – scanning or non-scanning, mechanical or non-mechanical, Flash LiDAR, Solid-state LiDAR or MEMS-LiDAR – all LiDAR systems have one thing in common: The interaction of the optics and sensor chip of the emitter and receiver unit of the LiDAR sensor must be absolutely precise and perfectly aligned.

If the components are not precisely positioned, objects and distances cannot be reliably detected. In the worst case, this could impair the safety of autonomous driving.

Accordingly, perfect performance must be ensured from the first sample to the series product. Jenoptik's subsidiary TRIOPTICS offers an ideal, application-oriented solution for the alignment and assembly of LiDAR systems, depending on the LiDAR type.

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 (= Light 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 (Scanning LiDAR) or simultaneously (non-scanning Flash LiDAR), depending on the LiDAR measurement method.

Flash LiDAR (Non-Scanning LiDAR)

Flash LiDAR sensors illuminate their field of view by means of a single expanded laser pulse or laser beam. The reflected laser light is then imaged on a detector array and 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, these sensors are robust, insensitive to vibrations and compact. For example, they can be easily integrated into autonomous vehicles also in large quantities.


Scanning LiDAR

Scanning LiDAR sensors scan the environment with many individual laser pulses. For this purpose, a collimated, 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, so-called MEMS, based on semiconductors are used as deflection optics. Disadvantages of these sensors are their bulky size, wear due to moving components, and also manufacturing costs.

Transmitter Optics for LiDAR Sensors

Polymer Objective Lenses

Transmitter optics

The LiDAR sensor’s transmitter optics have the task of shaping (i.e. collimating or expanding) the laser beam and directing it to the field of view (FOV) of the sensor, to be measured. Depending on the sensor type, the transmitter optics generate single laser spots, laser lines or illuminate the complete field of view of the sensor. Homogeneity and distortion-free imaging are prerequisites for reliable measurement data of the LiDAR sensor.

Our offerings and services include:

  • Transmitter optics with mirrors, lenses, diffractive or refractive optical elements (DOE, ROE) and microlens arrays (MLA)
  • Hybrid lenses. These combine the best properties of spherical, aspherical and free-form optics based on glass or plastic (polymers, polycarbonates)
  • Athermal lenses for temperature ranges from -40 °C to +110 °C
  • Optomechanical design of customer-specific lens systems
  • Imaging optics and collimators
  • Structured laser lighting (point, line, area)

Optical Diffusers for Flash LiDAR Sensors

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

Optical diffusers

Flash LiDAR sensors require homogeneous, full-area illumination of the field of view. To achieve this, the laser beam is expanded homogeneously by optical diffusers, and then projected onto the field of view (FOV) of the LiDAR sensor. Depending on the measurement geometry and sensor type, different diffusers are used for which we can offer you tailor-made solutions.
