Lidar system with suppressed doppler frequency shift

A light detection and ranging (LIDAR) system with supressed Doppler frequency shift, wherein the system comprises:

• at least one light source configured to emit a first light,
• at least one imaging input aperture and one imaging channel associated with the at least one imaging input aperture and configured to receive an input reflected light that is reflected by a moving object that is irradiated by the light source,
• at least one reference aperture and one reference channel associated with the at least one reference aperture and configured to receive a reference reflected light that is reflected by the moving object that is irradiated by the light source,
• at least one imaging oscillator,
• at least one imaging optical receiver associated with the imaging input aperture and the at least one imaging oscillator and configured to obtain an interference signal between the input reflected light and the at least one imaging oscillator,
• a reference oscillator, wherein the at least one imaging oscillator is separately modulated with respect to the reference oscillator,
• a reference optical receiver associated with the reference aperture and the reference oscillator and configured to obtain a reference interference signal between the reference reflected light and the reference oscillator, and
• at least one mixer, connected to the at least a first one imaging optical receiver and to the reference optical receiver and configured to produce an intermodulation product between the interference signal and the reference interference signal, such that the Doppler frequency shift caused by the moving object is cancelled or decreased.
