Solid State 3D LiDAR

Autonomous Vehicles and ADAS applications

The Challenge

Complete electronic design of a solid-state 3D LiDAR used in autonomous vehicles and ADAS applications.

Client: LeddarTech

Location: Quebec City, QC, Canada

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.

Frantz Saintellemy, President & COO

Founded in 2007, LeddarTech is a leader in optical detection and ranging technology at the forefront of the most exciting innovations in advanced sensing today.

This is how we do it

Our team at 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. The highly efficient multi-channel laser pulse driver circuits enabled lower power consumption and better heat dissipation.
