Product Overview

The automotive LiDAR encoder disc serves as the core precision component of the photoelectric encoder. Functioning as the “precise nerve center” for LiDAR scanning motion, it directly determines angular measurement accuracy and point cloud data quality. Manufactured using Precision Electroforming technology, the metal disc achieves micron/nanometer-level structural replication through metal ion deposition. This enables seamless compatibility with the high-speed scanning (up to 1200 RPM) and high-precision sensing requirements of rotary LiDAR systems. Designed for harsh in-vehicle conditions, this encoder features vibration resistance, extreme temperature tolerance, and electromagnetic interference immunity. It serves as a critical component for achieving 360° omnidirectional perception and precise environmental modeling in autonomous driving, widely deployed in LiDAR systems for passenger vehicles, commercial trucks, and autonomous trucks.

Core Features

Ultimate Precision, Fortifying Perception Foundations: Electroforming technology achieves encoder track width ±0.001mm and angular error <0.001°, with up to 24-bit angular resolution. This ensures precise spatial alignment for every laser beam emission and echo reception, providing core support for high-quality 3D point cloud construction.

Automotive-Grade Adaptability for Harsh Conditions: Operating temperatures span -40°C to 125°C, vibration resistance reaches 100G, and IP67 certification ensures reliability in extreme vehicle environments—including high/low temperatures, continuous vibration, and oil contamination—delivering maximum long-term stability.

Stress-Free Forming for Extended Lifespan: Non-contact chemical deposition eliminates mechanical stress and heat-affected zones, preventing encoder deformation and microcrack risks. Metal strength loss remains below 4%, with no performance degradation after 100,000 cycle tests. Service life exceeds traditional machined encoders by 3-5 times.

High-efficiency synchronization enhances data quality: Supports A/B/Z three-phase quadrature signals and 2MHz high-frequency output. 16x interpolation subdivision precisely coordinates laser emission, reception, and data acquisition timing, improving point cloud spatiotemporal consistency by 40% and effectively eliminating scanning distortion.

Flexible customization adapts to diverse requirements: Supports full-size customization with diameters ≤500mm and thicknesses 0.03-0.1mm. Compatible with multiple materials including copper, nickel, and nickel-cobalt alloys. Encoder track structure adjustable for LiDAR models (128-line / 512-line / 1080-line). Ensures over 99.7% yield rate for both small-batch and mass production.

Practical Application Outcomes

Perception Accuracy Leap: Lidars equipped with electroformed encoder discs achieve 3x higher point cloud density than traditional solutions. They reliably detect 14cm-tall obstacles (e.g., fallen tires, cardboard boxes) at 120m distances, with ranging accuracy controlled within ±2cm. This provides autonomous driving systems with 2-3 seconds of safety decision time.

Enhanced Motion Control Stability: During high-speed cruising (120 km/h) and rapid acceleration, the encoder precisely feeds back scanning angles. The LiDAR maintains scanning deviation <0.05°, ensuring point clouds remain sharp and jitter-free. This guarantees uncompromised perception performance in low-light conditions like nighttime, rain, or fog.

Meets automotive reliability standards: Passed dozens of tests including automotive-grade EMC, high/low temperature cycling, and mechanical shock. Operates flawlessly in extreme weather like sandstorms, rain, and snow, suitable for commercial applications like autonomous trucks and high-level intelligent driving vehicles.

Enhanced production efficiency: Roll-to-roll automated production lines integrated with AI vision inspection reduce batch production lead times to 7 days. Unit area costs are 40% lower than laser processing, while achieving 90% metal recovery rate, balancing cost-effectiveness and environmental sustainability.
