Shortwave Infrared - The Latest Weapon In The War On Terror
5/28/2009
Keeping one step ahead of our adversaries is top priority for security forces with terrorist threats growing daily around the world. Intelligence, surveillance and reconnaissance are the core situational awareness tools for the global war on terrorism (GWOT). By David G. Dawes

Article: NIR Trends: Machine Vision In The Short Wave Infrared
2/19/2009
Manufacturers have used cameras to monitor their processes since the first industrial cameras were made available. What do you do when there are no visible differences to distinguish good product from bad?

Technical Article: What You Should Ask Before Investing In A Shortwave Infrared (SWIR) Lens
1/30/2009
The military and industrial communities are investigating shortwave infrared (SWIR) technology for new and improved imaging solutions for a variety of challenging applications. Indium gallium arsenide (InGaAs) is a material often used for SWIR imaging due to its high quantum efficiency and low dark current. This advanced InGaAs material makes these detectors the most sensitive imagers that operate in the shortwave IR wavelength range at any given temperature. By MARC HANSEN

Article: NIR Trends: Penetrating The Haze Of Scattered Light
10/24/2008
In the July column of NIR Trends, we discussed the interaction of electromagnetic waves with materials they encounter, and how the interaction can tell us a great deal about the chemistry and physical makeup of those materials. This is the basis of most forms of spectroscopy. We went on to describe the impact NIR spectroscopy is having on our lives, particularly in biomedical imaging. In that context, light scattering was mentioned as a complication. This column will expand on the topic of light scattering and its impact on imaging with cameras at various wavelengths. Illustrations will compare images taken between visible and the shortwave infrared SWIR in haze, dust, and smoky conditions.

NIR Trends: The Growing Impact Of Light
7/24/2008
The interaction between an electromagnetic wave and a material can tell us a great deal about the chemistry and physical makeup of the material in question. We are all familiar with this interaction — for example, visible light in electromagnetic wavelengths reflects off plant leaves and enters our eye as green light, due to absorption of other wavelengths by the dominant photosynthesis chemical, chlorophyll. Fewer people, however, are aware that wavelengths in the infrared (IR) bands are also being used for product quality control and the detection of health problems.

White Paper: Non-Invasive Biomedical Imaging With FD-OCT
6/16/2008
Current medical practice poses a constant demand for development of non-contact, minimally invasive imaging techniques that can be used in clinics and hospitals for early diagnostics of various diseases and as an alternative to standard excisional biopsy. Optical coherence tomography (OCT) is a relatively novel imaging method that allows for non-invasive, cross-sectional imaging of the biological tissue structure with cellular level resolution and at depths of up to 1.5–2 mm below the surface.
