Device for Spatial Detection, in Particular Lidar Device

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention provides a Lidar device for three-dimensional detection of objects, using at least two optical waveguide units (such as glass fibers or Plexiglas rods) to direct back-reflected or back-scattered light pulses from different directions onto a detection surface, which is typically divided into multiple pixels. The system avoids moving mirrors by using fixed, curved light guides, simplifying construction and improving robustness, with applications such as in vehicles for environmental perception.

Use CasesContent extracted from patent full text and abstract with AI.

• Autonomous vehicles for environmental surround sensing and collision avoidance.
• Industrial robotics for three-dimensional object detection and distance measurement.
• Surveillance and security systems for area scanning and intrusion detection.
• Drones and UAVs for mapping and navigation.
• Atmospheric or environmental monitoring (e.g., particle or gas detection).
• Navigation systems for ships, aircraft, or ground vehicles.

BenefitsContent extracted from patent full text and abstract with AI.

• Simplified mechanical design compared to rotating mirror Lidar systems, reducing complexity and cost.
• Increased reliability and robustness by eliminating moving parts susceptible to wear or failure.
• Scalable and flexible coverage, allowing 360° (omnidirectional) or customized field-of-view configurations.
• High accuracy and spatial resolution through use of pixelated detection surfaces and time-of-flight analysis.
• Simultaneous multi-directional detection, reducing dead times (blind spots) common in rotating systems.
• Easier production, installation, and maintenance due to modular light guide structure.
• Improved data association and signal processing via coding of emitted pulses and pixel/channel assignment.

Patent Abstract

The invention relates to a device, in particular a LIDAR device, for the three-dimensional detection of an object and/or for determining characteristics by means of a back-reflected or back-scattered portion of at least one light pulse emitted by the device, said device comprising at least two optical waveguide units which can redirect a return light pulse of the back-reflected or back-scattered portion from different directions onto a detection surface.
