International Classification:

G01S 17/06
G01S 17/00
G01S 17/32

Abstract:

A lidar system with a pulsed laser diode to produce a plurality of optical seed pulses of light at one or more operating wavelengths between approximately 1400 nm and approximately 1600 nm. The lidar system may also include one or more optical amplifiers to amplify the optical seed pulses to produce a plurality of output optical pulses. Each optical amplifier may produce an amount of amplified spontaneous emission (ASE), and the output optical pulses may have characteristics comprising: a pulse repetition frequency of less than or equal to 100 MHz; a pulse duration of less than or equal to 20 nanoseconds; and a duty cycle of less than or equal to 1%. The lidar system may also include one or more optical filters to attenuate the ASE and a receiver to detect at least a portion of the output optical pulses scattered by a target located a distance.

Abstract:

A lidar system with a light source to emit a pulse of light and a receiver to detect a return pulse of light. The receiver can include a first channel to receive a first portion of the return pulse and produce a first digital output signal, and a second channel to receive a second portion of the return pulse and produce a second digital output signal. The receiver can include a logic circuit to produce an output electrical-edge signal in response to receiving the digital output signals. The receiver can also include a time-to-digital converter to determine a time interval based on an emission time of the pulse of light and based on the electrical-edge signal. The lidar system can also include a processor to determine a distance to a target based at least in part on the time interval.

Abstract:

A lidar system with a light source to emit a pulse of light into a field of view and a receiver to detect a return pulse of light which is reflected or scattered by a target in the field of view. The receiver may include an avalanche photodiode to generate an electrical-current pulse corresponding to the return pulse and a transimpedance amplifier to produce a voltage pulse that corresponds to the electrical-current pulse. A voltage amplifier may amplify the voltage pulse and a comparator may produce an edge signal when the amplified voltage pulse exceeds a threshold. A time-to-digital converter may determine a time interval based on an emission time of the pulse of light and based on the edge signal. A processor may determine a distance to the target using the time interval.
