If you’re looking for something new in photography, try hyperspectral imaging–a method that lets you capture electromagnetic spectrum of a particular object or location (imagine checking for mineral deposits from afar). It’s the same technology used by U.S. soldiers in conducting the raid of Osama bin Laden’s compound.
Hyperspectral sensors are very expensive equipment, but researchers from Vienna University of Technology created a hyperspectral camera from an ordinary DSLR camera: a Canon EOS 5D. The concoction, which combines a diffraction gel, stock SLR glass, PVC pipe, and duct tape, resulted to a computed tomography image spectrometer (CTIS).
The modified camera delivers a 4.89nm spectral resolution in a 120 x 120 pixels, but exposure time takes a little longer compared to commercially available hyperspectral imagers.
The researchers have proven that they can build a low-cost and compact hyperspectral device. Now they’re planning to create another version with less weight and shorter exposure time—with a price tag of just under $1,000.[Vienna University of Technology via Engadget, The Verge]
