A large scanning radiometer for characterizing fenestration systems

Conference ·
OSTI ID:5061707
A large scanning radiometer for measuring the bidirectional transmittance and reflectance of fenestration systems and components is described. Examples of measured data obtained for simple non-specular samples using the radiometer are presented. A method of obtaining the overall bidirectional properties of systems by calculation from scanning radiometer measurements of components is suggested. Advantages and limitations of the method are discussed. The method appears promising.
