Abstract: Techniques of deriving audio signals using frequency modulated continuous-wave (FMCW) LIDAR use an acceleration-based algorithm in which an audio signal is based on a difference in velocity between two up-chirps or two-down-chirps. Such an acceleration-based algorithm takes less computation, results in fast processing, boosts the high frequency component of the audio signals which the velocity-based algorithm lacks, and improves the subjective intelligibility. For example, in the acceleration-based algorithm, the DC components may be safely ignored in many cases. In such cases, the system does not require a band-pass filter as in the conventional systems, thus reducing computational burden. Moreover, the acceleration-based algorithm emphasizes high frequencies that form a more realistic depiction of human speech.
