Complete electronic design of a solid state 3D LiDAR used in autonomous vehicles and ADAS applications
- Extremely short schedule to design the electronics of an automotive grade LiDAR reference solution from scratch.
- Exceedingly small footprint while maintaining long range performance requirements with stringent packaging and power consumption constraints.
- Multiple new components (ASIC, optics, SoC) being developed simultaneously with the electronics.
The Breakthrough Innovation
Orthogone came up with an extremely compact electronic design while using low cost PCB technologies. By using mixed-signal, high-performance receiver chains with very low noise and high-dynamic range, we were able to provide more accurate and longer range detection. And, the highly efficient multi-channel laser pulse driver circuits enabled lower power consumption and better heat dissipation.
