We propose a multi-input LiDAR receiver that is capable of cancelling optical interference in the physical layer. This system leverages a blind source separation (BSS) technique to generate de-mixing parameters that can be implemented using photonic analog circuitry to separate interference signals from incoming ToF LiDAR pulses in real time. The system is capable of removing wideband optical noise in the form of environmental interference, free-space optical communication signals, other LiDAR sensors, and adversarial LiDAR spoofing devices without appreciably affecting the throughput of the sensor.
