It is possible that the neutral test card instructions include a correction for specular reflections.
The specular reflection off the surface of glass or plastic is about 4-5% of the incident light.
An object's specular reflection can be captured using computer controlled lights and sensors.
Many common materials exhibit a mixture of specular and diffuse reflection.
Waves other than visible light can also exhibit specular reflection.
A perfect sail is flat and has 100% specular reflection.
This refers to elastic scattering rather than to a specular reflection.
This provides uniform lighting and reduces specular reflection, keeping glare low.
This form of the potential guarantees a specular reflection on the boundary.
The radar echo is generated by specular reflections from the sea surface.
