Spectral Sciences Incorporated is a research and development

Research and development

The phrase research and development , according to the Organization for Economic Co-operation and Development, refers to "creative work undertaken on a systematic basis in order to increase the stock of knowledge, including knowledge of man, culture and society, and the use of this stock of...

 company, located in Burlington, Massachusetts, United States.

Spectral Sciences was founded in 1981. Its primary focus is the development of concepts and prototype scientific software and instrumentation. Clients include the US Government as well as industry

Industry

Industry refers to the production of an economic good or service within an economy.-Industrial sectors:There are four key industrial economic sectors: the primary sector, largely raw material extraction industries such as mining and farming; the secondary sector, involving refining, construction,...

.

Areas of expertise include electro-optic remote sensing

Remote sensing

Remote sensing is the acquisition of information about an object or phenomenon, without making physical contact with the object. In modern usage, the term generally refers to the use of aerial sensor technologies to detect and classify objects on Earth by means of propagated signals Remote sensing...

, atmospheric radiation transport, the science of combustion

Combustion

Combustion or burning is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species. The release of heat can result in the production of light in the form of either glowing or a flame...

, computational physics

Computational physics

Computational physics is the study and implementation of numerical algorithms to solve problems in physics for which a quantitative theory already exists...

, chemistry

Chemistry

Chemistry is the science of matter, especially its chemical reactions, but also its composition, structure and properties. Chemistry is concerned with atoms and their interactions with other atoms, and particularly with the properties of chemical bonds....

 and molecular dynamics

Molecular dynamics

Molecular dynamics is a computer simulation of physical movements of atoms and molecules. The atoms and molecules are allowed to interact for a period of time, giving a view of the motion of the atoms...

, energy management

Energy management

Energy Management is a degree offered by the University of Oklahoma's Michael F. Price College of Business. The OU degree program was the first of its kind, emerging in 1958 as the Petroleum Land Management program before becoming the Energy Management program in 1999.It is business-specific, with...

, 3-D and spectral scene modeling, spectroscopy

Spectroscopy

Spectroscopy is the study of the interaction between matter and radiated energy. Historically, spectroscopy originated through the study of visible light dispersed according to its wavelength, e.g., by a prism. Later the concept was expanded greatly to comprise any interaction with radiative...

, UV

Ultraviolet

Ultraviolet light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 400 nm, and energies from 3 eV to 124 eV...

 through IR

Infrared

Infrared light is electromagnetic radiation with a wavelength longer than that of visible light, measured from the nominal edge of visible red light at 0.74 micrometres , and extending conventionally to 300 µm...

 optical signature analysis, tomography

Tomography

Tomography refers to imaging by sections or sectioning, through the use of any kind of penetrating wave. A device used in tomography is called a tomograph, while the image produced is a tomogram. The method is used in radiology, archaeology, biology, geophysics, oceanography, materials science,...

 methods and analysis and electro-optical instrumentation development in support of phenomenological studies and new measurement concepts.

Software developed by SSI and available to the public include:

FLAASH and QUAC, atmospheric correction codes which calculate spectrally resolved ground reflectance from hyperspectral imaging

Hyperspectral imaging

Hyperspectral imaging collects and processes information from across the electromagnetic spectrum. Much as the human eye sees visible light in three bands , spectral imaging divides the spectrum into many more bands...

 and multispectral imaging. Both codes are available as the Atmospheric Correction Module plug-in for ENVI.

MODTRAN

MODTRAN

MODTRAN is a computer program designed to model atmospheric propagation of electromagnetic radiation for the 100-50,000 cm-1 spectral range....
