LOW COST HYPERSPECTRAL IMAGING AT UNIS F. Sigernes The University Centre on Svalbard, Norway

SCENARIO 1. 2. 3. 4. 5. 6. 7. SVALSAT is well established. All polar satellites in field of view. Longyearbyen airport. Local airborne carriers. AGF-207, AGF-331 & AGF-218 Logistics Cryo. Wing UAV w/ NORUT IT = REMOTE SENSING

PRINCIPLE

KEY OPTICAL ELEMENT The grating equation is modified by using Snell’s law where m is the spectral order, l is the wavelength, a the groove spacing, a the incident angle and b the diffracted angle. Wavelength l [nm] Refractive index n Diffracted angle b [deg. ] BP [ nm] Linear dispersion dl/dx [nm/mm] 300 1. 61829 38. 9872 0. 63 37. 9174 400 1. 58942 33. 6908 0. 74 48. 0392 500 1. 57606 29. 2111 0. 80 53. 9186 600 1. 56880 25. 1126 0. 82 57. 7198 700 1. 56442 21. 2360 0. 83 60. 3967 800 1. 56158 17. 5051 0. 84 62. 3734 900 1. 55963 13. 8757 0. 85 63. 8542
