An FOFC is a stabilized pulse laser. In other words, an FOFC is a phase-coherent combination of several hundreds of thousands of wavelengths. Therefore, this fact means that there are several hundreds of thousands of different wavelengths and their combination, adjacent pulse repetition interval length (APRIL), which can be used as a length scale. Based on this idea, we proposed the APRIL-based method. APRIL-based length measurement method uses an APRIL (the physical length associated with the pulse repetition period) as a ruler for measuring distance. In this work, we show how the uncertainty in length conversion is affected by the change in environmental parameters via the sensitivity coefficients of refractive index under an actual experimental environment. |
