We demonstrated an optical method to evaluate the state of asphalt due to the presence of atmospheric agents using the measurement of the polarization/depolarization state of near infrared radiation. Different sensing geometries were studied to determine the most efficient ones in terms of performance, reliability and compactness. Our results showed that we could distinguish between a safe surface and three different dangerous surfaces, demonstrating the reliability and selectivity of the proposed approach and its suitability for implementing a sensor.
我们展示了一种使用近红外辐射的偏振/去偏振状态测量来评估大气物质对沥青状态的光学评估方法。研究了不同的传感几何形状,以确定在性能、可靠性和紧凑性方面最有效的几何形状。我们的结果表明,我们可以区分安全表面和三种不同的危险表面,证明了所提出方法的可靠性和选择性及其用于实现传感器的适用性。
