Abstract
A heterogeneous THz-QCL is used for 4-frequency diffuse-reflectance imaging of powdered sugars and polymers. An effective-optical-path model reproduces features in the Beer–Lambert absorption spectra accurately and discriminates between admixtures of materials with differing concentration.
