Abstract
A portable field spectrometer designed for measuring the spectral reflectance signatures of terrain objects is described. The instrument employs a chopping technique rendering possible the simultaneous measurement of irradiance from sun and sky on one hand and radiance from the scene on the other. This enhances the applicability of the instrument during variable irradiance conditions caused by drifting clouds. The instrument operates over the 340–2500-nm spectral region. Examples of measuring results are given.Keywords
