Abstract: A light detection and ranging (lidar) system may include a transceiver, a first device including a laser source configured to generate a beam, and one or more optical components, a second device including one or more analog-to-digital converters (ADCs), and a processor configured to alternately turn on the first device and turn on the transceiver. The first device may be configured to generate, based on the beam, an optical signal associated with a local oscillator (LO) signal. The transceiver may be configured to transmit the optical signal to an environment, in response to transmitting the optical signal, receive a returned optical signal that is reflected from an object in the environment, and pair the returned optical signal with the LO signal to generate an electrical signal. The second device may be configured to generate, based on the electrical signal, a digital signal.
