Classification: CPC G | IPC G

Claim 19:
20. The multiplexed LiDAR system of claim 9 wherein the LiDAR module comprises:
a first coupler configured to receive the pulsed wavelength-modulated coherent light from the coherent light source and configured to divide the pulsed wavelength-modulated coherent light into a first portion of the pulsed wavelength-modulated coherent light and a second portion of the pulsed wavelength-modulated coherent light;
a circulator connected to receive the first portion of the pulsed wavelength-modulated coherent light and configured such that the first portion of the pulsed wavelength-modulated coherent light enters a first port of the circulator and exits from the subsequent port to direct the first portion of the pulsed wavelength-modulated coherent light to the scanner;
a sample arm connected to the first coupler to receive the first portion of the pulsed wavelength-modulated coherent light and transfer the first portion of the pulsed wavelength-modulated coherent light to the scanner;
a reference arm connected to the first coupler to receive the second portion of the pulsed wavelength-modulated coherent light; and
a second coupler configured to receive the back-reflected portion of the pulsed wavelength modulated coherent light, configured to receive the second portion of the pulsed wavelength modulated coherent light from the reference arm, and configured to couple the back-reflected portion of the pulsed wavelength modulated coherent light and the second portion of the pulsed wavelength modulated coherent light to form an optical interference signal; and
a photodetector array configured to receive the optical interference signal and convert the optical interference signal to an electrical interference signal.
