Abstract
A distributed FM LiDAR system that provides a central unit that includes a frequency modulated optical signal source and a central receiver for reflected light, along with multiple optical heads that include only optical components is described. No optical delay lines or timing compensation photonic or electronic circuitry is necessary between the central unit and the optical heads. The relatively simple optical heads do not require extensive protection from shock or vibration, and can be distributed between a vehicle and a towed trailer or similar vehicle, with connections being provided by an optical coupling.
