Demonstration of Frequency Bandwidth

Contents:
  • The Optical Microphone is able to detect the entire acoustic frequency bandwidth which is transmitted through air
  • High frequencies often contain significant process-quality information
  • Hence, disturbing background noise (low frequencies) can be separated from process information (high frequencies)
