The high-precision measure of length for range-finding on the base of electromagnetic radiation

Summary form only given, as follows. The wave measure of length on the base of superposition of two electromagnetic monochromatic oscillations having different frequencies is proposed for increasing the precision of the lengths, which are more than 100 m, measurements. The introduction of such measure of length into the metrological practice will permit to realize the structure of metrological assurance of linear measurements on the new conceptual base which assure not only increase of large lengths measurement precision, but also the direct connection with the primary standard of the unit of length.
