Abstract
We propose a new concept for an unconventional type of two-color method for interferometry-based length measurements based on the adjacent pulse repetition interval length (APRIL), which is the physical length associated with the pulse repetition period. We demonstrate by numerical simulations that if the wavelength-based two-color method can eliminate the inhomogeneous disturbance of effects caused by the phase refractive index, then the APRIL-based two-color method can eliminate the air turbulence of errors induced by the group refractive index. We show that our analysis will benefit the pulse-laser-based two-color method, which secures traceability to the definition of the meter.
