Microsoft is working on cheap hyperspectral camera for smartphones




Microsoft is working with the University of Washington with a hyperspectral camera that should be inexpensive to produce and must fit in a smartphone. Such a camera may for example be used for biometric identification.

The camera from Microsoft and the University of Washington, called hypercam, can light with seventeen different wavelengths emit and perceive in both the visible spectrum and the human eye invisible near-infrared spectrum. As a result, the camera can pick up which details with the naked eye hardly or not can be perceived. When the camera is directed to human hands, for example, to certain wavelengths, the veins under the skin very clearly visible. In yet a different wavelength, the structure of the skin with all the wrinkles and folds can be seen clearly. At that time, it is also the pulsation of the skin by the heart rate to see well with, for example, the arteries.
