Patent ID: 11397252

Abstract:
An oscillator system includes a transmitter configured to transmit a frequency modulated continuous wave (FMCW) light beam along a transmission path, where the FMCW light beam includes a plurality of wavelength ramps and a wavelength of the FMCW light beam continuously varies over time; an oscillator structure configured to oscillate about a scanning axis based on a deflection angle of the oscillator structure that continuously varies over time; and a dispersive element arranged in the transmission path and configured to receive the FMCW light beam and output a compensated FMCW light beam along the transmission path, where the dispersive element is configured to compensate for a propagation direction disturbance caused by an oscillation of the oscillator structure. The oscillator structure is arranged in the transmission path and is configured to direct the FMCW light beam or the compensated FMCW light beam towards an output of the transmission path.
