HawkSpex® Mobile takes an entirely different but surprisingly simple route. A combination of adjustable illumination and a color camera, a kind of inverse spectroscopy, disperses light in narrowband spectral channels. This is fundamental to the implementation of hyperspectral scanning.
To do this, the smartphone’s display switches to a sequence of different colors in rapid succession on its entire display and synchronously takes pictures with the front camera, thus measuring the light reflected by the defi ned illuminated target object. The sequence of lighting colors produces a spectral image in fractions of a second.
Specially developed methods of artificial intelligence convert the recorded raw spectral data into information in the context of the concrete application. An app enables user interaction, synchronizes illumination and picture-taking, and establishes a connection to a spectral application database.
