TechInsights publishes a teardown of Intel RealSense L515 LiDAR:

“The Intel RealSense L515 is rated for indoor use and can provide depth measurements between 0.25 m and 9 m with a field of view of 70° x 55°. Its LiDAR unit consists of an IR (860 nm) laser reflecting off a scanning MEMS mirror, coupled with an IR photodiode. It is also fitted with an RGB camera which provides a 1080p resolution at 30 fps.”

RealSense L515 Teardown

Once open, we were able to identify the following design wins:

MEMS Design Win: STM PM56A

The optical board hosts 2 major components of the LiDAR: the edge emitting laser, and the MEMS mirror die mounted between 4 permanent magnets.

What is the cost of the hardware in the RealSense L515?

Our costing specialists assembled the following cost breakdown for the L515.

Conclusion

MEMS-based laser scanning LiDAR cameras can provide an effective way of reducing electronics costs while improving the overall reliability of these devices. The inclusion of this technology in the RealSense L515 allows Intel to pursue logistics and robotics markets, where more expensive and fragile technologies may not be as widely adopted. TechInsights has additional analysis available on this technology, including cross-sectional analysis of the MEMS die, which can be found here.
