I. Architectural Innovation and Reliability Breakthroughs  

Ouster's digital LiDAR revolutionizes traditional solutions with a fully chipized architecture, employing custom SoCs (containing SPAD detector arrays) and VCSEL laser arrays to replace thousands of discrete components. This enables single-photon-level detection and digital signal processing. Contactless electromagnetic power supply (no slip rings) eliminates mechanical wear, while sub-pixel redundancy design ensures that local component failures do not affect overall performance. The REV7 series has a mean time to failure (MTTF) exceeding 250,000 hours, far surpassing the 1,000–3,000 hours of traditional mechanical LiDAR. Built-in self-diagnosis functions and the use of automotive-grade standards for 95% of components further enhance reliability in industrial scenarios.  

II. High-Performance Multimodal Sensing Capability  

(1) Core Performance Metrics  

The REV7 series achieves fine-grained environmental capture with 128-line vertical resolution, a point frequency of 5.2 million points/second, and a frame rate of 10–20 Hz. It covers a detection range of 20–200 meters (10% reflectivity) and supports zero-blind-zone near-field detection (e.g., OS0 with 0m blind zone). Its wide field of view (OSDome’s 180° vertical field of view) and centimeter-level accuracy (±0.5–10 cm) adapt to diverse needs from close-range collision avoidance to long-range monitoring.  

(2) Multimodal Data Fusion  

It synchronously outputs 3D point clouds, ambient light near-infrared images, active intensity images, calibrated reflectivity, and IMU data, providing full-dimensional information on geometry, texture, material, and motion for algorithms. For example, reflectivity data can distinguish material types, while IMU data supports LIO-SAM/SLAM algorithms for motion compensation and high-precision positioning without additional sensor fusion.  

(3) Flexible Configuration Capability  

It supports software-defined parameters such as horizontal resolution (512–4096), frame rate, multi-echo mode, and 3D zone monitoring (REV7 supports 128 predefined zones). The same hardware can adapt to multiple scenarios like collision avoidance, navigation, and security, reducing development complexity.  

III. Robust Design for Extreme Environments  

(1) Synergistic Advantages of Wavelength and Architecture  

The 865nm wavelength has a water vapor absorption rate only 1/5 of 1550nm. Combined with a large optical aperture and multi-echo technology, it significantly outperforms traditional solutions in penetration through dust, fog, and steam. In high-humidity steam scenarios like train unloading, it can stably detect residual frozen coal.  

(2) Environmental Adaptability Parameters  

Temperature: Operates in a wide temperature range of -40°C to +60°C, with some REV7 models reaching up to +70°C. It starts at low temperatures without heating, suitable for winter conditions in northern ports.  

Protection: IP68/IP69K protection ratings resist high-pressure washing and long-term immersion, while stainless steel interfaces enhance corrosion resistance in salt雾 environments.  

Mechanical Strength: Withstands 100g冲击 and 5Grms vibration, suitable for heavy machinery vibration scenarios.  

(3) Special Scenario Optimization  

REV7 enhances dark target detection capability by 7x (e.g., black tires) through the L3 chip, optimizes reflectivity calibration accuracy to reduce "halos" on high-reflective edges and missed detection of low-reflective objects, and features anti-glare design for stable operation under direct sunlight.  

IV. Integration Benefits and TCO Advantages  

(1) Simplified System Architecture  

In many 3D sensing applications (e.g., all-around collision avoidance, autonomous navigation), traditional solutions often require combining multiple 2D LiDARs, cameras, radars, and even PTUs and independent IMUs to achieve required coverage and functions. However, single or fewer Ouster 3D LiDARs (e.g., OS0, OS1, or OSDome), with their wide field of view, high resolution, and built-in IMU, often replace such complex setups.  

(2) Full Lifecycle Cost Optimization  

BOM Cost: Reduced sensor count directly lowers hardware procurement costs. While Ouster 3D LiDAR has a higher unit price than basic 2D sensors, replacing multiple sensors and auxiliary devices (e.g., PTU, high-performance IMU) can持平 or even reduce total BOM costs.  

Integration and Cabling Installation Costs: Fewer sensors mean simpler mounting bracket design, simplified power and data cabling, and fewer interface requirements, saving significant engineering design, installation, and debugging time and costs.  

Calibration and Software Development Costs: Reduced sensor count and Ouster’s inherent factory calibration and multimodal data synchronization greatly reduce the workload and complexity of multi-sensor calibration (internal/external parameters, time synchronization). Software only needs to handle fewer and more standardized data sources.  

Maintenance and Operation Costs: This is the core of Ouster’s TCO advantage. Its extremely high reliability (MTTF > 250,000 hours) and rugged design (IP68/69K, anti-shock/vibration) mean minimal failure rates and long service life. In contrast, less reliable mechanical scanners or PTUs may require frequent repairs or replacements, leading to high spare parts costs, maintenance labor, and—more importantly—production downtime losses. Ouster LiDAR’s low-maintenance features significantly reduce lifecycle operation costs.  

V. Core Upgrades of the REV7 Platform  

(1) Performance Leap  

Detection Range Doubled: OS1 detects 10% reflectivity targets from 45m to 90m, and OS2 reaches 200m.  

Point Frequency and Accuracy: Point frequency increased to 5.2 million points/second, accuracy improved by 50% (e.g., OS1 typical error ±0.5–3 cm).  

Zero Blind Zone Design: OS0/OS1 achieve 0m blind zone, significantly enhancing near-field collision avoidance reliability.  

(2) Enhanced Functions  

OSDome Models: 180°×360° hemispherical field of view eliminates top blind zones, suitable for AGV perimeter protection.  

On-Chip Intelligence: Supports real-time monitoring of 128 3D detection zones and directly outputs trigger signals, simplifying collision avoidance logic development.  

Automotive-Grade Adaptation: New vehicle Ethernet interface and 95% automotive-grade components pave the way for autonomous driving scenarios.  

(3) Energy Efficiency and Reliability  

10% lower power consumption, 2x improved shock and vibration resistance compared to previous generations, and structural optimization for long-term stability balance high performance and low energy consumption.  

VI. Conclusion: Technical Differentiation and Industry Value  

Through the 865nm wavelength selection, fully chipized architecture, and REV7 platform innovation, Ouster systematically addresses the core pain points of bulk material handling scenarios:  

Replaces 2D LiDAR: 3D coverage eliminates vertical blind zones, with single sensors replacing multi-device setups.  

Outperforms vision solutions: Stable operation in dust/rain/fog, protects privacy, and directly outputs distance data.  

Cost Advantage: TCO reduced by over 40% compared to traditional solutions, with reliability driving long-term benefits.  

Its technology portfolio not only adapts to industrial scenarios like ports and mines but also expands to intelligent transportation through automotive-grade upgrades, becoming a key enabling technology to push automation toward high precision and robustness.
