Ouster OS1-32 Rev7 SR

Key Features

• Digital LiDAR Architecture: Utilizes Ouster’s proprietary L3 chip with back-side-illumination technology, boasting significant improvements over previous generations, including higher photon sensitivity and enhanced digital signal processing.
• Vertical Resolution: The OS1-32 specifically features 32 channels of vertical resolution. Other OS1 models offer 64 or 128 channels.
• Mid-Range Performance: The sensor is designed for mid-range applications, offering an impressive blend of distance and detail.
  • Maximum Representable Range: Up to 207 m.
  • Range (at 10% Lambertian reflectivity): Approximately 45 m (in 1024 @ 10 Hz mode, with >90% detection probability in 100 klx sunlight).
  • Minimum Range: $0.3\text{ m}$ (configurable, $0.5\text{ m}$ default).
• High Angular Accuracy: Features high precision with an angular sampling accuracy of $\pm0.01^\circ$ (Vertical and Horizontal).
• Field of View (FOV):
  • Horizontal: $360^\circ$ (Full surround view).
  • Vertical: $42.4^\circ$ ($\pm 1.0^\circ$).
• High Configurability:
  • Horizontal Resolution: Configurable to 512, 1024, or 2048 points per scan.
  • Rotation Rate: Configurable to 10 Hz or 20 Hz.
  • Dual Return Mode: Provides two returns per laser pulse (strongest and second strongest), improving object detection, especially in environments with small or semi-transparent obstacles.
• Imaging Data: Captures rich data per point, including Range, Signal, Reflectivity, and Near-infrared (NIR), giving it camera-grade imaging capability alongside 3D point cloud data.

Robustness and Integration

The OS1-32 Rev7 SR is built for real-world reliability and easy integration:

• Environmental Protection: Designed for all-weather, indoor/outdoor use with an IP68 and IP69K ingress protection rating, making it highly resistant to dust and water submersion/high-pressure spray.
• Operational Durability: Exhibits high resistance to shock and vibration, with an operating temperature range of $-40^\circ\text{C}$ to $+60^\circ\text{C}$.
• Compact Form Factor: It is one of the smallest high-performance LiDAR sensors on the market, facilitating direct integration into size- and weight-constrained platforms like robots, drones, and fixed infrastructure.
• Software Ecosystem: Supports development with the Ouster SDK, open-source ROS, and C++ drivers, ensuring seamless integration into existing and new projects.

The Ouster OS1-32 Rev7 SR offers an industry-leading combination of size, weight, power, and high resolution performance, making it a robust and scalable solution for a wide range of autonomous and sensing applications.
