This technology is a new method of measuring Fresnel reflection in the total amount of reflected and scattered light off a surface. Unlike existing methods, this method requires the measurement of only two parameters, and therefore is simpler and requires less expensive equipment than existing methods. Background: Fresnel reflection is the reflection of a portion of the light off of a surface with a different refractive index than it has previously been traveling in, such as light hitting a glass windshield. When the light is reflected, the polarization properties of the light change. These new properties can then be measured and used to ascertain information about the surface the light reflected off of.
