Hyperspectral Imaging Cameras


Typically, hyperspectral cameras operate in the visible, near-infrared (NIR) and the short-wavelength infrared part of the electromagnetic spectrum (SWIR). In these spectral regions they acquire three-dimensional datasets in which a spectral profile is available for each pixel in the image. Depending on the location in the spectrum different types of information can be extracted from plants, ranging from water content to cell structure and leaf pigments, such as chlorophyll and anthocyanins. Such information can be calculated based on a plethora of known spectral indices, but the analysis of complete spectral profiles is likely return even more.

Both visible – NIR (VNIR) and SWIR hyperspectral cameras, providing full,contiguous spectral information for each pixel, are offered. These cameras are mounted on a moving stage and work as push- broom type line scanners. Such a close-range hyperspectral imaging setup comes with dedicated illumination units ensuring homogeneous plant illumination.
