A organisation of imaging specialists over at Vienna University of Technology has advance up with a hyperspectral camera using materials that are simply accessible, inclusive channel tape. The project, called Computer Tomography Image Spectrometer (CTIS), attaches a hyperspectral camera lens done of batch SLR glass, a jelly diffraction filter, PVC pipe, and channel tape, in to an common DSLR camera.
For the uninformed, hyperspectral imaging is a photography way that captures a significantly larger amount of electromagnetic spectrum compared to a periodic photo. It is used for a accumulation of purposes, inclusive night prophesy together with identifying vegetable deposits from long distances. However, building a hyperspectral imager does not advance cheap, thus this plan provides an cheap alternative.
The CTIS takes hyperspectral images by slipping light rays in to bright bands using a diffuser and recording them in to a camera in HDR mode, in this box the Canon EOS 5D Mark I. The antecedent can takeover a bright fortitude of up to 4.89nm in a 120 x 120 pixel area, but it requires a longer bearing time compared to its blurb counterparts. The investigate team is in the routine of shortening its weight whilst increaing the orifice for a shorter bearing time.
