selective reflection
The reflection in different amounts as a function of wavelength, as a result of absorption and scattering, leading to color effects if occurring in the visible wavelength region.
specular reflection
Pertaining to the manner in which light is reflected, as by a mirror or speculum.
surface reflection
Also known as Fresnel reflection. That portion of the incident radiation that is reflected from the surface of a refractive material. It is a function of the refractive index of the material. At...

specular reflection
Pertaining to the manner in which light is reflected, as by a mirror or speculum.
scattered light filter
A specific type of filter designed to reduce the amount of light scattered by reflections from the edges of optical components or mounts, or from irregularities on the optical surfaces.
Secondary Speckle Pattern
A self-interference effect that generates random patterns; secondary speckle pattern (SSP) typically occurs in diffuse reflections of a laser on paper, white paint or rough surfaces. By tracking both...
silver spots
Spots in a polished glass surface that are opaque and have a silvery, metallic reflection.
slab laser
Solid-state laser geometry in which the standard rod is replaced by a slab of laser material. Often called total-internal-reflection face-pumped laser (TIR-FPL).
SLAR
side-looking airborne radar; single-layer antireflection
soft coating
A term describing an antireflection coating that may be applied to optics that cannot tolerate the high temperatures usually required for normal "hard'' coatings. Such coatings lack durability...
spectral signature
A spectral signature, in the context of remote sensing and spectroscopy, refers to the unique pattern or characteristic spectral response of a material or object across different wavelengths of the...
spectrophotometry
Study of the reflection or transmission properties of specimens as a function of wavelength.
