Abstract
A coherent lidar system includes a light source to output a continuous wave, and a modulator to modulate a frequency of the continuous wave and provide a frequency modulated continuous wave (FMCW) signal. The system also includes an aperture lens to obtain a receive beam resulting from a reflection of an output signal obtained from the FMCW signal, and an optical amplifier in a path of the receive beam to output an amplified receive beam. A method of fabricating the system includes arranging a light source to output a continuous wave, and disposing elements to modulate the continuous wave and provide the FMCW signal. The method also includes arranging an aperture to obtain a receive beam resulting from a reflection of an output signal obtained from the FMCW signal, and disposing an optical amplifier in a path of the receive beam to output an amplified receive beam.
