Abstract
When lddenotes an initial optical path length that is a length of an optical path, along which the signal light travels, as converted using a refractive index in vacuum, lmdenotes an initial optical path length that is a length of an optical path, along which the reference light travels, as converted using a refractive index in vacuum, Δl denotes a fluctuation width of a difference in optical path lengths between the signal light and the reference light as converted using a refractive index in vacuum, λdenotes a central oscillation wavelength of the wavelength-variable laser, and Δλ denotes an oscillation wavelength variable range of the wavelength-variable laser, then an initial optical path difference |ld−lm| satisfies |ld−lm|>(Δl/Δλ)λ.
