Systems, devices, and methods employing angular-resolved scattering and spectrally resolved measurements for classification of objects

Abstract

Systems, devices, and methods are described for identifying, classifying, differentiating, etc., objects. For example a hyperspectral imaging system can include a dark-field module operably coupled to at least one of an optical assembly, a dark-field illuminator, and a hyperspectral imaging module. The dark-field module can include circuitry having one or more sensors operable to acquire one or more dark-field micrographs associated with scattered electromagnetic energy from an object interrogated by the dark-field interrogation stimulus. The hyperspectral imaging module can be operably coupled to the dark-field module, and can include circuitry configured to generate an angular-resolved and spectrally resolved scattering matrix based on the one or more dark-field micrographs of the object.
