the article is a bit light on real details, but all the affordable LIDAR technology I have seen used Linear-Feedback Shift Registers, such that different devices operating at the same frequency are still on different channels.
It's unclear if this product works in the time-domain or in the frequency domain...

- DoctorOetker 8y agothanks, that is helpful!
- mtreiber 8y agoShorter range lidars (<10m) tend to work in the frequency domain because you can get pretty good ranging accuracy. Longer range lidars work in the time domain. The SPAD detectors used by Ouster create a pulse when a single photon is detected and so you're measuring the time of flight of the photon being emitted by the vscel and then being detected by the SPAD array.
