1. An imaging system, comprising:
a photonic circuit chip that includes multiple cores that each includes a port through which an outgoing light signal exits the photonic circuit chip,
each of the cores is configured such that the outgoing light signal exits the photonic circuit chip traveling toward a location that is above or below the photonic circuit chip,
each of the cores configured to combine light from one of the outgoing light signals with a reference signal so as to generate a signal beating at a beat frequency; and
electronics that use the beat frequencies from the cores to calculate data that indicates a radial velocity and/or distance between one or more objects located outside of the imaging system and the imaging system.
