Abstract :
This paper reports on the development of an ultrahigh accuracy distance meter (femtosecond-comb distance meter (FCDM)) with a simple setup and reliability for a practical measurement using a broad and stable femtosecond frequency comb. The distance meter is expected for a length standard as well as industrial applications. In this study, a 2-/spl mu/m uncertainty in the FCDM by using 10-GHz beat frequencies is achieved.
