Electronic Distance Measuring Instruments

163
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 assess the suitability of quartz transducers as standards for ultrasonic power measurement.
  • To conduct an international intercomparison of continuous-wave (cw) power measurements using these standards.

Main Methods:

  • Seven international laboratories participated in the study.
  • Each lab performed measurements using their standard practices.
  • National Bureau of Standards served as the pilot laboratory for data collection.

Main Results:

  • Results from the intercomparison were compiled and presented.
  • Data indicates the potential of quartz transducers as reliable ultrasonic power standards.
  • Observations on the stability of the transducers were also noted.

Conclusions:

  • The intercomparison validates the use of specific quartz transducers as standards for ultrasonic power.
  • Consistent measurement results across laboratories support their reliability.
  • Further stability analysis provides additional confidence in their application.
