Absorptance, английский
- In illumination engineering, the ratio of the absorbed flux to the incident flux. absorption 1. the process by which a liquid, or a mixture of gases and liquid, is drawn into and tends to fill permeable pores in a porous solid material; usually accompanied by a physical change, chemical change, or both, of the material. 2. the increase in weight of a porous solid body resulting from the penetration of liquid into its permeable pores. 3. the increase in weight of a brick or tile unit when immersed in either cold or boiling water for a stated length of time; expressed as a percentage of the weight of the dry unit. 4. the process by which radiant energy, which is incident on a surface, is converted to other forms of energy. 5.

Spectral, английский
Prefix used to denote a variable that changes as a function of wavelength.
Spectral absorption; factor, английский
Spectral analysis, английский
A form of time series analysis that treats the observed sequence of events or measurements as being analogous to a radio or similar signal. the signal is assumed to be a mix of "pure" signals at various frequencies and the model estimates the power (amplitude) at the various frequencies. typically the signals are represented by a fourier series, a mixture of sine and cosine functions. other basis functions can also be used, such as hadamard functions (which take on values of 1 and -1) or wavelets. see also: time series analysis, box-jenkins analysis.

Spectral beam combining, английский
A class of methods for beam combining, based on wavelength-sensitive beam combiners
Spectral brightness, английский
Brightness per unit optical bandwidth
Spectral color analysis technique, английский
Метод цветоспектрального анализа
Spectral coverage, английский
The number of spectral bands and their associated spectral resolution needed to faithfully extract target information.
Spectral curve, английский
A color's "fingerprint" (a visual representation of a color's spectral data. a spectral curve is plotted on a grid comprised of a vertical axis); and a horizontal axis (the visible spectrum of wavelengths. the percentage of reflected light is pl
Spectral data, английский
The most precise description of the color of an object. an object's color appearance results from light being changed by an object and reflected to a viewer. spectral data is a description of how the reflected light was changed. the percentage of reflecte

Spectral irradiance, английский
- Measure of energy emitted by a radiation source as function of wavelength. units of spectral irradiance are watts per square meter and are often plotted versus wavelength.
