AUDIO DETECTION SYSTEM AND METHODS

摘要

A laser microphone can include a detection system including plurality of laser subsystems. The detection system can be configured to produce emitted electromagnetic radiation based on a frequency pattern and receive reflected electromagnetic radiation reflected from an object. The detection system can be configured to define combined frequency data based on a frequency of the emitted, electromagnetic radiation and a frequency of the reflected electromagnetic radiation. The detection system can be configured to define a set of spectral bins in a frequency domain based on the combined frequency data, modify the combined frequency data based on a datapoint obtained from a subset of the set of spectral bins, and define at least one of a range or a velocity based on the combined frequency data. The laser microphone can include an audio processor configured to define an audio signal based on the at least one of the range or velocity.
