  • LOW COST HYPERSPECTRAL IMAGING AT UNISF. Sigernes

    The University Centre on Svalbard, Norway

  • SCENARIOSVALSAT is well established.All polar satellites in field of view.Longyearbyen airport.Local airborne carriers.AGF-207, AGF-331 & AGF-218LogisticsCryoWing UAV w/ NORUT IT= REMOTE SENSING

  • PRINCIPLE

  • The grating equation is modified by using Snells law

    where m is the spectral order, l is the wavelength, a the groove spacing, a the incident angle and b the diffracted angle. KEY OPTICAL ELEMENT
