mettus Posted May 22, 2015 Report Share Posted May 22, 2015 Hi! I have partable usb-spectrometer with optical fiber (similar like ocean optics device) and plan to use it in the fields for getting soil and vegetation spectra. I am planning to build spectral library with my area of intarest typical spectras and use it for hyperspectral data analysis (hyperion). Please advice me, how to use it in the fields right way? I have try to get spectras using 15x15cm white teflon card as reflectance reference (near 100% reflectance), but I see there is difference in spectras dependent on angle and distance between fiber and surface. And I can not anderstand how estimate field-of-view of 600nm optical fiber and have to keep it very close to teflon card and ground or vegetation. Please help me with links, books or good advise!

anggik Posted June 1, 2015 Report Share Posted June 1, 2015 hi mettus do you have the tutorial from the spectro producer? I think you will get the proper method there for ground survey by using those product Quote Link to comment Share on other sites More sharing options...
