FMCW lidar: The Next Leap in Physical AI

The rise of Artificial Intelligence (AI) is transforming industries,but true intelligence requires more than just data processing. It demands a deep understanding of the physical world. This is where lidar – Light Detection and Ranging – comes into play, and a new generation of Frequency Modulated Continuous Wave (FMCW) lidar is poised to revolutionize how AI perceives and interacts wiht it’s surroundings. Voyant is at the forefront of this innovation, aiming to replicate the impact the CMOS camera had on the digital imaging revolution.

Understanding the Physical AI Revolution

The “Physical AI” revolution refers to the integration of AI with real-world sensing and actuation. Unlike traditional AI focused on digital data, Physical AI requires systems that can accurately perceive, understand, and respond to the physical environment. This is crucial for applications like autonomous vehicles, robotics, industrial automation, and smart infrastructure. Current LiDAR technologies, while effective, have limitations in range, resolution, and interference immunity – hindering the full potential of Physical AI.

What is FMCW LiDAR and Why is it Different?

LiDAR technology works by emitting light pulses and measuring the time it takes for them to return, creating a 3D map of the environment. There are different types of LiDAR, but FMCW LiDAR represents a notable advancement. Here’s a breakdown:

• Traditional LiDAR (Pulsed LiDAR): Sends out short pulses of light. Measures time-of-flight to determine distance. Susceptible to interference from other LiDARs and sunlight.
• FMCW LiDAR: Continuously emits a modulated light signal, sweeping through a range of frequencies. Measures both the time-of-flight and the frequency shift of the reflected signal.

This frequency shift measurement is the key differentiator. It allows FMCW LiDAR to:

• Measure Velocity Directly: FMCW LiDAR can determine the speed of objects,a critical capability for autonomous systems.
• improve Interference Immunity: The continuous wave signal and frequency modulation make it far less susceptible to interference from other LiDARs or ambient light.
• Enhance Range and Resolution: FMCW LiDAR can achieve longer ranges and higher resolutions compared to traditional pulsed LiDAR.

Voyant’s Role in Advancing FMCW LiDAR

Voyant is pioneering a new generation of FMCW lidar specifically designed to overcome the limitations of existing technologies. Their approach focuses on:

• CMOS Compatibility: Leveraging the established manufacturing processes of CMOS (Complementary Metal-Oxide-Semiconductor) technology, similar to how CMOS revolutionized camera sensors. This enables scalability and cost reduction.
• High-Performance Silicon Photonics: Utilizing silicon photonics to create compact, efficient, and high-bandwidth optical components.
• Advanced Signal Processing: Developing sophisticated algorithms to extract accurate data from the FMCW signal, even in challenging environments.

By emulating the CMOS camera revolution, Voyant aims to make high-performance LiDAR accessible for a wider range of applications, accelerating the adoption of Physical AI.

Applications of Next-Generation FMCW LiDAR
