Abstract: In some implementations, a light detection and ranging (LIDAR) system includes a laser source configured to provide an optical signal at a first signal power, an amplifier having a plurality of gain levels, at which the amplifier is configured to amplify the optical signal, and one or more processors. The one or more processors are configured to, based on the first signal power and a duty cycle of the optical signal, vary a gain level of the amplifier from the plurality of gain levels to generate a pulse signal, transmit the pulse signal from the amplifier to an environment, receive a reflected signal that is reflected from an object, responsive to transmitting the pulse signal, and determine a range to the object based on an electrical signal associated with the reflected signal.

Abstract: A light detection and ranging (lidar) system for a vehicle may include a receiver layer, a transmitter layer coupled to the receiver layer through an adhesive layer in a first direction, and one or more optics. The transmitter layer may receive, at a first side of the transmitter layer, a transmit signal from a laser source, and transmit the transmit signal through the one or more optics. The receiver layer may receive, through the one or more optics, a return signal reflected by an object in an environment of the vehicle, and output the return signal at a first side of the receiver layer. The first side of the transmitter layer and the first side of the receiver layer may be apart from and parallel to each other in a second direction crossing the first direction.

Abstract: A light detection and ranging (lidar) system for a vehicle may include an input optical path, a first optical path, a plurality of second optical paths, a first optical amplifier, and a plurality of second optical amplifiers. The input optical path may be configured to receive a beam from a laser source. The first optical path and the plurality of second optical paths may be respectively branched from the input optical path. The first optical amplifier may be coupled to the first optical path and configured to output a local oscillator (LO) signal. The plurality of second optical amplifiers may be respectively coupled to the plurality of second optical paths, one of the plurality of second optical amplifiers being selectively turned on to modulate the beam received through a second optical path and output a modulated optical signal of the beam.
