It can be seen that the scaling is very effective at flattening the diffuse reflection component and thereby making the specular component more visible against that flat background.
Then, the work tackles the interpretation of combination and overtone bands in the near-IR range (7500-4000 [cm.sup.-1]), where the diffuse reflection phenomenon is dominant.
Specular reflection is generally more polarized than diffuse reflection. [16]
Life is more of a rough mirror's diffuse reflection.
A gaseous atom can interact briefly with a photon and this can result in diffuse reflection or scattering.
The sea surface becomes rougher when the wind speed increases, which causes an increase of the diffuse reflection. Consequently, the scattered energy is more widely distributed in nonspecular scattering directions.
Instead of using a diffuse reflection constant [k.sub.d], we use the radiance coefficient [r.sub.c] of the equation of Hapke's model (see (1)) to represent the ratio of the mineral in different phase angles.
In order to know the optical properties, we test the UVVisible diffuse reflection spectra (DRS) and monochromatic incident photon-to-electron conversion efficiency (IPCE) of the Ti[O.sub.2] films.
There are two types reflection of light which are specular reflection and diffuse reflection. The reflected rays are same and parallel to one another is known as specular reflection.
The accessory mounts in the sample compartment of the spectrometer and can operate in diffuse reflection or transmission modes.
The 85[degrees] is for low gloss levels (high diffuse reflection) or matte surfaces.
