| Popis: | We present a method of calculating the measurement variance-covariance matrix of a spectroscopic sample's complex refractive index from time-domain statistics in order to estimate uncertainty of a measurement. We compare this method to a numerical analysis and previously derived methodology, and show that our time-based estimate is both accurate and adaptable to complex extraction models. |
