Abstract :
This paper describes a new interferometer that is being developed for the velocity measurement of the BIPM watt balance. An Iodine stabilized Nd:YAG laser is used together with space separated heterodyning techniques to allow for small nonlinear errors and high phase resolution. First results will be presented.
