Abstract:
A road condition monitoring system capable of measuring the radiance reflected by an area of interest or the thermal radiance emitted by an area of interest in wavelengths range containing a crossover point between the curves representing the absorption of electromagnetic radiation by ice and water. A detector configured to measure the radiance in a first band having wavelengths in a spectral band on a first side of the crossover point and output a first band signal, and measure the radiance in a second band having wavelengths in a spectral band on a second opposing side of the crossover point and output a second band signal. A data processing unit configured to determine the ratio of the first band signal to the second band signal and compare the ratio to predetermined critical ratios to output a determination signal indicating the presence of water or various types of ice.

Claim (Index 13):
A method for detecting the road condition ahead of a vehicle or the condition of a surface of interest, comprising:\n measuring radiance in a first band and a second band adjacent to a crossover point of the imaginary part of the index of refraction of liquid water and ice and outputting a first band signal and a second band signal respectively, the radiance in the first band having wavelengths in a spectral band on a first side of the crossover point and in the second band having wavelengths in a spectral band on a second opposing side of the crossover point; adjusting the location and width of the first band and the second band based on slopes of the imaginary parts of the indexes of refraction of liquid water and ice between opposing sides of the crossover point such that water pushes the first band signal and the second band signal in the opposite direction than ice; and determining the ratio of the first band signal to the second band signal and comparing the ratio to predetermined critical ratios to output a determination signal indicating the presence of water or ice.
