Voyant has announced the Helium family of fully solid-state 4D FMCW LiDAR sensors and modules for simultaneous depth and velocity measurement. Based on a proprietary silicon photonic chip, the platform provides scalable sensing and high-resolution point-cloud data.

Helium employs a dense 2D photonic focal plane array with integrated 2D on-chip beam steering, enabling fully electronic scanning. A 2D array of surface emitters implements FMCW operation in a compact, solid-state architecture with no moving parts.
Key advantages of Helium include:
- Configurable planar array resolution: 12,000–100,000 pixels
- FMCW operation with per-pixel radial velocity measurement
- Software-defined LiDAR enabling adaptive scan patterns and regions of interest
- Ultra-compact form factor: <150 g mass, <50 cm³ volume
Helium sensors and modules will be available in multiple resolution and range configurations, supporting FoVs ranging from up to 180° wide to narrow long-range optics.
Voyant is offering early access to Helium for collaborators to explore custom chip resolutions, FoVs, module configurations, multi-sensor fusion, and software-defined scanning. To participate or request more information, contact earlyaccess@voyantphotonics.com.
