The size of the vehicle was 640 mm x 400 mm x 180 mm and was able to carry the necessary equipment for the range of tasks required, including pre-inspection(More)
A theoretical analysis of long-term drift noise in Fourier transform spectroscopy is presented. Theoretical predictions are confirmed by experiment. Fractional Brownian motion is employed as a stochastic process model for drift noise. A formulation of minimum detectable signal is given that properly accounts for drift noise. The spectral exponent of the(More)
