Basic Working Principles of Electronic Distance Meters

  • J. M. Rüeger

EDM instruments are classified according to the type of carrier wave employed. Instruments using light or IR waves are classified as electro-optical instruments. Instruments based on radio waves are generally called microwave instruments. Because of the different structure of these two types of instruments, they will be discussed separately.
