Method of Determining Fractional Contribution by Fresnel Reflection Using Two Measurements
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...
