Technical Article: Short-wave IR Offers Unique Remote Sensing Solutions
5/19/2006
The shortwave infrared (SWIR) wavelength band is rich in potential for solving imaging challenges in measurement, inspection, and process-monitoring tasks. Spectral signatures in the SWIR can reveal the presence of contaminants or moisture in agricultural products. Hot-furnace processes and walls can be inspected through ordinary safety glass enclosures or with off-the-shelf glass lenses or optics. Glass manufacturers can image in the SWIR at high speed, monitoring the cooling process to identify costly defects inside bottles before waste costs balloon...

Using SWIR To Detect Disguises At Border And Immigration Checkpoints
As the U.S. continues to increase its security at border crossings, airports, and other points of entry, biometrics will play an important role. SWIR cameras can help identify disguises at the border and therefore supplement security efforts.
