Standard Spectral Reflectance Measurements for ASD FieldSpec Spectroradiometer

Accurate and precise spectral measurements represent the objective material's properties. But some of the factors that are responsible for change in spectral signature which has effect on the quality of spectral measurement. These factors should be taken into consideration while taking measurement. These factors include environmental and experimental issues, the properties of the atmosphere, timing, orientation, and height of measurement, Field Of View (FOV), calibration of the spectral data and spectral averaging etc. This paper defines method for standard spectral reflectance measurements and the factors affecting the measurement.
