The ASD FieldSpec 4 Hi-Res is a high resolution spectroradiometer designed for faster, more precise spectral data measurements for a wide array of remote sensing applications. Overview The 3 nm VNIR, 8 nm SWIR spectral resolution of the ASD FieldSpec 4 Hi-Res spectroradiometer provides superior spectral performance across the full range solar irradiance spectrum (350 – 2500 nm). The enhanced spectral resolution in the SWIR range (1000 – 2500 nm) is particularly useful for detecting and identifying compounds with narrow spectral features in the longer wavelengths such as alteration mineralogy and gases for atmospheric analysis. Additionally the 8 nm resolution meets or exceeds the spectral resolution of most hyperspectral sensors making the ASD FieldSpec 4 Hi-Res spectroradiometer an excellent choice for sensor validation and calibration, as well as ground truthing and building spectral libraries. Like all ASD FieldSpec spectroradiometers, the ASD FieldSpec 4 Hi-Res can be used as a high resolution spectrometer for very accurate contact reflectance measurements. Key applications The ASD FieldSpec 4 Hi-Res NG spectrometer can be used in many industry applications, including: Plant Physiology ASD systems are used to determine plant physiological status, including disease status, nutritional status related to nitrogen uptake and moisture balance. Camouflage Characterization and Detection The detection of camouflaged or hidden objects requires a measurement that provides a contrast between the object and background materials.
