Electronic Distance Measuring Instruments

188
Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over...

Purpose of the Study:

  • To investigate the performance of retro-reflective film as an acoustic membrane for LDV-based sensing.
  • To develop a remote acoustic sensing apparatus with minimal physical intervention.
  • To demonstrate the feasibility of this apparatus in practical applications.

Main Methods:

  • Theoretical analysis and systematic experiments were conducted on a retro-reflective film membrane.
  • A Laser Doppler Vibrometer (LDV) was used to measure the vibration of the film.
  • The apparatus was tested for sound pressure level sensing and active noise control.

Main Results:

  • The developed apparatus can sense sound pressure levels above 20 dB within the 200 Hz to 4 kHz frequency range.
  • Demonstrated applications include remote speech signal sensing and an active noise control headrest.
  • A significant 22.4 dB noise reduction was achieved in the active noise control system (300 Hz to 6 kHz).

Conclusions:

  • Retro-reflective film coupled with LDV provides a viable, minimally invasive remote acoustic sensing solution.
  • The system offers advantages over traditional microphones, particularly in challenging acoustic environments.
  • The technology shows significant potential for diverse applications in acoustic sensing and control.
