Optics and Lasers in Engineering, 158, 107172.0143-8166https://hdl.handle.net/10016/37115A pavement condition sensor aims to estimate the pavement surface grip, and therefore the sensor must detect the presence of water, snow, slush or the like on the surface of the pavement. The leading technology for such a sensor is near infrared diffuse reflectance spectroscopy using a wavelength range around a water absorption peak. In this paper we present a pavement condition sensor based on said technique that uses an electro-optic dual optical frequency comb generator as optical source. The proposed sensor provides unique properties in terms of measuring integration time that are necessary to advance the pavement condition several meters ahead of a moving vehicle.9eng© 2022 The Author(s).Atribución-NoComercial-SinDerivadas 3.0 EspañaDual-comb spectroscopyElectro-optic frequency comb generatorPavement condition sensorresearch articleElectrónicaFísicaIngeniería Industrialhttps://doi.org/10.1016/j.optlaseng.2022.107172open access11071729Optics and Lasers in Engineering158AR/0000031835
