SWIR And The U-2
8/4/2016
The U-2 spy plane is the leading reconnaissance platform for the United States. The camera used in today’s U-2, SYERS, uses electronic sensors to see in both the mid-wave infrared (MWIR) band (thermal energy) and the short wave infrared (SWIR) band (reflected light).

The Third Infrared Window
8/4/2016
Long wave infrared (LWIR) and mid-wave infrared (MWIR) sensors and cameras have been used in military settings for detecting human activity through thermal emissions. Using the short wave infrared (SWIR) portion of the spectrum extends unique capabilities that often compliment LWIR and MWIR imaging.

Detecting And Defeating Subversive Night And Fog Activities
4/8/2013
Around-the-clock surveillance capability in any weather is a decisive operational ad-vantage for military and emergency services. In these and similar applications, SWIR cameras are well-suited for everyday use because they show good results when compared with other imaging technologies. To recognize and track objects of light-reflecting as well as self-radiating natures, SWIR cameras can be easily combined with thermal LWIR cameras and their images overlaid to enhance their content and validity.

Expanding The Dynamic Range Of Short Wave Infrared (SWIR) Imagery
1/22/2010
Advances have been made in short wave infrared (SWIR) imaging technology to address the most demanding imaging and surveillance applications. Multiple techniques have been developed and deployed in Goodrich’s SWIR indium gallium arsenide (InGaAs) cameras to increase the dynamic range performance of standard, commercial off-theshelf (COTS) products.
