Title: A CCD based bidirectional spectral reflectance field instrument
Author: Davis, Michael H.
Abstract: Accurate interpretation and maximum use of multispectral data acquired from spaceborne and aircraft instruments require increased knowledge and understanding of the bidirectional reflectance distribution function (BRDF) of earth scene elements. Knowledge of the relationships between the spectral characteristics and important parameters of earth surface features can best be obtained by carefully controlled studies over areas, fields or plots where complete data describing the condition of targets is attainable and where frequent, timely spectral measurements can be made. The Bidirectional Spectral Reflectometer (BuSTeR) described in this thesis was developed to provide the Digital Imaging and Remote Sensing Laboratory (DIRS) with the capability to obtain multispectral BRDF data from field targets. Topics in this thesis include the design goals of the optical, mechanical and electronic components, equipment calibration, options and capabilities provided through the software package and final performance evaluation of BuSTeR, including spectral resolution and responsivity, sensitivity to polarization, field of view, system linearity, noise performance and dynamic range.
